Hello doc, I'm an Engineering student and my day starts at 5 30AM and ends 12AM(Mid night). i just get 5 - 6 hours sleep. I always get angry at everything, even at very tiny things. Even i realize its little things but even i get angry and shout. This loses friends etc.. I dont have anyone to share my feelings or anything. I always end to be alone and feel lonely. I am sad and crying for no reason. Whenever others make fun of me , my minds goes to wrong activities like commiting suicide. HelpME
