I wanted to share my own experience. I've had a mild panic attack after my tonsillectomy operation. I couldn't talk to people and smile, I've had heart palpitations constantly, not only during that attack, my muscles were tired all the time, I couldn't eat anything solid, I couldn't stop thinking about the palpitation because it became like a music to me, a continous rythym. anyway, my finals were coming up and I got up and dressed unwillingly with my mother not letting me stay. I did a little studying, I got up, went to school and took the exam. After I was out, I saw a donut shop and felt my appetite coming back first time in those days. Then my symptoms actually vanished. I understood that you need to get on with your everyday life no matter what. Making excuses and sitting at home only gets you depressed. Depression is not without a cause (excluding the genetic one's) and I think that one should look at his/her life and mind for that cause to cure it. I went to school and saw my girlfriend and everything got better by day Being useful is the way to go I think
