Dear user, welcome to lybrate-user. Clinical depression or depressive disorder is a neurochemical disorder. Clinical depression is usually treated with a combination of psychiatric medicines, psychotherapy, life style changes, meditation and exercise. I hope you are undergoing psychiatric treatment, otherwise, please approach a psychiatrist. Once you make the necessary amendments in your life with the help of the above said therapies and life style changes, learn how to manage the depressive episodes without medicines and learn to relax, the medicines can be weaned off over a period of one year.

5 Types of Common Depression

Depression is a very common emotion you might have experienced at least once during your lifetime. Depression refers to a state of mind when you are feeling low due to persistent sadness and loss of interest. But if the depression is chronic and long lasting for you, then it indicates that you are suffering from clinical depression. Under clinical depression, it is preferable that you go through a proper treatment course by a certified therapist. The Most common types of depressions are:

  1. Major depression - Under this type of a depression you will be depressed for most days of the week and if this condition extends for a period greater than 2 weeks, then it is a case of major depression. The most common method to treat a major depression is to talk to a mental health specialist and take medications called antidepressants (only after a prescription by a certified doctor).
  2. Persistent depressive disorder - This is a more severe and long lasting type of depression which is identified if you are depressed over a period longer than 2 hours. The most common symptoms of this type of a disorder are - change in your appetite, too much or too little sleep, lack of energy or fatigue, low self-esteem, trouble concentrating or making decisions, feeling hopeless among others.
  3. Bipolar disorder - If you are experiencing extreme ups and downs of mood abruptly and without any apparent reason, then you might be suffering from this disorder. This disorder is commonly known as a maniac depression, because during an up phase you will be extremely happy, joyful outgoing and talkative but during the low phase you will be sad, tired and depressed.
  4. Seasonal affective disorder - This type of a depression might bother you only during the winter season. This happens whenever the days are shorter and your body is not able to get enough of sunlight. This mostly happens in the case of people who are very fond of sunlight, and they prefer the sunshine over dark periods of the night. This disorder is treated by SAD antidepressants and everyday light therapy of 15 to 20 minutes.
  5. Psychotic depression - Under this type of a depression, you will have a major depression along with some psychotic symptoms like - hallucinations, delusions, and paranoia. Hallucinations mean viewing things that are not there, in reality, delusions are false beliefs or misconceptions and paranoia is the constant fear that somebody is going to harm you.

I am 19 years old lady I got recently love marriage but my parents didn't agree him and I am unable to take decision who is important to me? in that case I couldn't take decision to my life please give suggestion that how to take decision.

Hypnotherapist, DCS, BSIC, Advanced Trainee of Transactional Analysis, Advanced Skills in Counselling
Each relationship has its own place and importance. They are not comparable rather they supplement and complement each other. You are playing dual role of daughter and wife. Try to maintain respect for everyone including yourself and your decisions. Don't force your husband on your parents. Gradually when they see that you loved and meant to marry him, they might turn around. Remember that you do have the right to marry of your own choice. What you need to be sure of is your reasons for marrying this boy.

My jiju is having a serious problem of brain mental disorder and how treat it at home please suggests me as soon as possible.

Hypnotherapist, DCS, BSIC, Advanced Trainee of Transactional Analysis, Advanced Skills in Counselling
Dear, I understand that you are worried for his health and immediate treatment. But first he will need to see a psychiatrist and a counsellor to understand and diagnose what mental problem he has. After the diagnosis, treatment with medication, home remedies, stress counselling can be suggested. Counselling is a confidential and unbiased space for the client to talk and learn to solve their problems in an effective way without feeling too much tension. But, for any illness, eating a healthy diet, which is suitable to the patients needs is the first step. After that, exercising like walking, running, swimming is suggested for the fitness of body and mind. He might need some rest for mental, physical and emotional recuperation. I suggest that he could take a brief holiday to disconnect from his tensions, but later try to learn productive ways to either resolve or cope with his stress triggers.

My mom is 41 years old. From the last year my mom started crying during the sleep. Earlier it happened from 2 months but now it started happening in 15 days. In the mid night she started crying. Even last night she started crying. We consulted the physician he said that may be it is due to the gas problem. I need an advice from psychiatrist what we have to do.

Homeopath, Raebareli
You need to clearly identify what is bothering her - any nightmare/dreams of someone dying/any headache, etc. I suggest you give her nux vom 30 - twice daily for some days and revert back.

I am 22 and am about to join a job. want to live an independent lie and not think about marriage .My parents however keep bringing up this topic and this immediately sets my mood off and I start answering rudely. I had a very huge fight with my mother and everyone thinks it's my fault. Is it wrong to have my own opinion and wanting to live my life on my own? Can marriage not be only my decision? Am I really wrong?

Masters in Psychology, PGDRP
Psychologist, Delhi
Marriage is definitely a very personal choice and it should always happen for the right reason - that is, when you are mentally, emotionally and physically ready for it. There is nothing wrong in wanting to get married late, but getting rude or losing your cool, is not going to help. You need to convince your parents by explaining them your reasons. They are your parents, they love you and want the very best for you so communicate with them in a manner that they understand.

I am taking antidepressant since 5 years. How long should I need it. When I stopped to take it under the advice of my psychiatrist I was depressed.

Reparenting Technique, BA, BEd
Psychologist, Bangalore
I am glad that you followed the doctor's advise even though it did not work. Even so you can still pick up the pieces and start afresh. My advice is for to seek counseling in tandem with the medication. It is grossly inadequate to rely on medication alone. Counseling will teach you a lot of coping skills and techniques to manage the daily challenges of life. This is a passive way to hope for recovery. You must be active and work towards your reformation. Many lifestyle changes need to be made to progress away for the condition. Then, if you go episode-free for three years under the combination of medicine and therapy, you could initiate weaning off of the medication gradually and under strict monitoring of the psychiatrist. But it is never too late, and now you have a clear agenda and time plan to resolve the depression. In the meantime please do the following: When you are depressed, you will feel lazy though I would like to call it lethargy. There is an inertia and lack of energy to even think, let alone act. You are required to literally do the opposite of what you feel like doing. Depression makes you want to withdraw, lie down, sleep, become lethargic, slow down, make you too lazy to even think etc. So when I suggested doing the opposite, you will need to fight this disease. You must become active; stay upright during the daylight time; meet people; never sleep during the day, wake up by 6 am every day, play some active games, especially contact games, do physical exercises, talk to people and join some social clubs, eat more of proteins and vegetables, attend Yoga classes etc. Watch sitcoms on TV or comedies and cheer yourself up. Go for excursions in groups, for outings, camps, conferences, and religious conventions. Get a pet dog and spend time training it, exercising it and relating to it. Expose yourself to some sunlight every day, at least 30 minutes but not in the scotching heat. I hope you can find someone to love and be loved too. Whatever happens, please incorporate these three important adaptations in your life: always be responsible, be respectful, and be functional. If you did these three things, lots of things will go well in life. Please pray and have faith in God to alleviate your sufferings. Don’t wait for others to help. Use your own motivation, which might be at its lowest, but persevere and win this battle. Be prayerful too and trust that God will intervene too. Do not worry about your colleagues’ progress. You have been handicapped by this disease and your belief system due to this disease. Now go out there and win your battle: nothing is too late in life.

I can not understanding what am studying. My exams are near. What I studied is forgetting. What I want to do?

C.S.C, D.C.H, M.B.B.S
General Physician,
10 Study Tips to Improve Your Learning Study Tip 1: Underlining Underlining is one of the simplest and best known study tips. It’s easy to highlight the most significant parts of what you’re reading. One key sentence per paragraph and a few important phrases here and there. You can only retain a certain amount so it’s best to retain the most important information. Study Tip 2: Make your own note and taking notes is one of the most widespread study skills out there. Essentially the aim of note-taking is to summarise lectures or articles in your own words so you can easily remember the ideas. Study Tip 3: Mind mapping A good Mind map can save you many hours of study and further consolidate your knowledge for your exams. Mind Maps are an extremely versatile tools. They can be used for brainstorming, outlining essays or study topics and for general exam preparation, ExamTime offers the ability to create Mind Maps quickly and easily which makes them the ideal tool when it comes to exams. Study Tip 4: Flash cards:- Using these are a particularly effective method of learning when trying to assimilate different facts, dates, formulas or vocabulary. Subjects such as History, Physics, Maths, Chemistry, Geography or any language are made much easier if you incorporate Flashcards in to your study. Study Tip 5: Case Studies Sometimes it can be difficult to grasp the implications of some theories. This is where studying case studies can be a big help. Case studies can help you visualise a theory and place it in a more familiar and realistic context. This is especially useful in business or law subjects. Study Tip 6: Quizzes are an excellent way to review study notes in the weeks and days before an exam. Quizzes can show where your strengths and weaknesses are, so it allows you to focus your efforts more precisely. Moreover, if you share your Study Quiz with your classmates and test each other as much as possible you can discover even more details and areas you may have overlooked. So before any exam, make sure you create and share a bunch of different Quizzes with your Friends. Study Tip 7: Brainstorming This is another study technique that is ideal for studying with friends and/or classmates. Brainstorming is a great way to expand every possible idea out of any topic. Just get a bunch of friends together and shoot the breeze, there are no wrong answers when brainstorming – just talk and capture the ideas, you can review afterward. Study Tip 8: Mnemonic Rules Mnemonics are especially useful when memorising lists and sets. Mnemonics rules basically work by associating certain concepts with other concepts that are more familiar to us. There are many different ways to make mnemonics and these can be individual to the person. Study Tip 9: ORGANISE your study One of the most effective study skills is also one of the most often overlooked; this is organising your study. Creating a TIME TABLE gives you goals and a time in which to achieve them. Having a study timetable as you study is greatly motivational Study Tip 10: Drawing Many people find it easier to recall images rather than text that is why they are better able to memorise concepts if they associate them with pictures or drawings.

If you want to accept her, accept her completely then there should be no room of how she has been in those 5 years. Apart from that you need to trust her to build your relationship again, otherwise just let it go because this doubt may always be there and may lead to unhealthy relationship.

How Workout is the Best Way to Get Over Your Anger?

How Workout is the Best Way to Get Over Your Anger?

Anger is an ordinary and is an expressed reaction to an attack, perceived danger or fear. It has been very useful in our struggle for survival. The brain distinguishes the danger and the body is provoked and energized to respond with battle or fight. Once in a while, obviously, it gets out of hand. A few people, unmistakably, see dangers where there are none or where the risk is negligible. Their bodies get provoked improperly. They could use some assistance in understanding the signs that trigger their reactions and discover approaches to improve control.

Health problems: There are some individuals who encounter so much anger that they cannot control their drive to strike out at other people. This is isolated and separated from the issue of alcohol and medication misuse. It is imperative to recall that in case that you are a person who effectively gets angry and has outbursts, you can hurt your health.

Aerobics: Many of us are aware of the advantageous impacts that workout has on one’s well-being and health. Various studies exhibit that every day exercise, particularly a program that includes aerobic exercise, can counteract or lessen feelings of anger or depression. Aerobic exercises, much like cardio activities, such as running, brisk walking, swimming and bike riding gets a person out of breath while expanding the pulse and heart rate.

Muscle relaxation: Muscle relaxation requires you to concentrate on straining and unwinding specific muscle groups in your body, so that it can divert you from your sentiments of anger. Moreover, it is great for mitigating nervousness and pressure, which can likewise ease angry emotions. This activity additionally attempts to help you rest when your emotions are running high. Concentrate on a specific muscle group, for example, the muscles in one hand. While breathing in profoundly and gradually, crush the muscles as hard as you can and keep up that pressure for five seconds. For instance, straining your hand muscles would include shaping a tight clench hand. Concentrate on that gathering of muscles and make an effort not to unintentionally tense the surrounding muscles.

30 minutes: There is a lot to be gained even from a 30 minute routine at the gym, in the recreation center or at home. If you have any sort of medical condition, or if you are not sure about the condition of your health, you must consult your doctor. When you get medicinal freedom for activities, it helps arranging and using a work out timetable of no less than thrice each week.

All things considered, you do not have anything to lose except excess weight, depression and now, perhaps even anger. Along these lines, in case that you need to better deal with your anger as it emerges, a great workout might be the correct approach.

I am 30 years old and I am suffering from forgetting things,how can i get my mind sharp.

Reparenting Technique, BA, BEd
Psychologist, Bangalore
You may be under some stress, and I do not know if you are aware of it. Find out what this disturbance is all about and as you address it, memory and concentration will happily return to favor you. Do meet with a counselor, if your stress is too much. In the meantime please follow the suggested guidelines: Daily exercise of at least half an hour is a must. Even if you go to a gym, ask for aerobic and/or calisthenics exercises with whatever else you are doing. A healthy body harbors a healthy mind. With regard to memory, it is very important that your brain and body is ideally rested to be able to recall whatever is required, rather comfortably. Puzzles pose problems to the brain that help it to use new pathways and neurons, which give the brain considerable exercise. It taxes the left brain to use logic to solve the myriad possibilities which other activities do not stimulate. Crosswords are excellent for vocabulary learning and use. Jigsaws and Rubik cube stimulate different permutations to finally settle on the most likely one. Picture completion and anagrams help approach problem solving from several angles. Do Sudoku, and memory co-relation activities and skills. Have a good night’s sleep, have a good breakfast of more proteins, meditate often, remain free of stress, eat a lot of fiber (whole grains, fruits and vegetables), nuts, avocado, eat dark chocolate, consume less of fat and use olive oil or coconut oil instead, do Yoga meditation exercises, etc. You need to check out if you are stronger visual or auditory. The visual is a better mode than the auditory. However, if you combine the two modes, you will get the best concentration. Short-term memory is a faculty of the left brain, and long-term memory is a feature of the right brain. But you must have short term memory to convert it into long-term memory. So the emphasis must be in activating good short term memory, ideally and always. When people are stressed, they tend to favor the right brain and abandon the left brain, where short-term memory resides. So, it is really very simple: deal with the stress and activate left brain functions. Here are a few suggestions to activate left brain function: shut your left nostril and breathe, move your eyes from right to left and vice versa for at least half a minute at a time, and do callisthenic exercises with some form of counting, regularly. If your home life is full of distractions and stress, it is likely to affect your memory, adversely. In that case, I suggest that you and the family go for counseling too.
