Hello Doctor, I'm 21 years old and a student. I won't be able to sleep at nights properly and have a lot of jerks in between. I sometimes wake up for a bad dream also. I will be having headache almost all the time throughout the day. I sometimes wake up myself crying and during the day time as well I cry a lot of times without reason or even for a very small reason. I won't be able to concentrate on any thing and feel restless and hopeless all the time. I get too cranky, upset and tensed even for a small thing and over think a lot about it. Please help me out with this problem. Thank you.
