Of course it will get better. But keep in touch with your doctor and inform him/her of your symptoms because some medicines are required only for some time and if that time has exceeded, then it may need to be discontinued. The medicines for your diabetes is good and there is some depression and some anxiety which is also being treated and that is good too. The tension and lack of sleep is not a good sign. I suggest that you meet with a counselor and address the emotions concerned with them. Most likely it may have to do with fear and anger. The counselor will train you to handle these feelings and if they have origins from childhood, there may have to be more work therapeutically for your full recovery. Life is full of problems as a norm. Any attempts to escape will never help: you must learn to face these problems every day with good success. The counselor will help you in this regard. I also strongly believe that every crisis offers an opportunity for change, if you seek it and grab the opportunity. Please meet with a counselor and work on your emotions, particularly anger and fear. Exercise is very important but you have to build on it developmentally. I suggest you do the opposite of what this depression makes you feel like doing (actually, not doing): you will need to fight this condition. 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, 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 scorching heat. Whatever happens, please incorporate these three important adaptations in your life: always be responsible, be respectful, and be functional. If you did these three, 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. Above all to be really happy, you need to live in love and for love. Learn all about emotions and how to handle them and that will get you out of the depression rather easily and quickly. A counselor is there only to facilitate you, all the hard work must come from you, and your cooperation with that person is very critical for your success. Be positive every day and learn to be content with what you have. If you tend to sleep late, do avoid that and wake up at a uniform time even if you don't get sleep. Whatever happens please cooperate with the therapy and do not discontinue until the condition is completely resolved.
