Hello sir, I am 19 years old female. From last 5-6 months I have been having excessive mood swings, for one moment I feel like I am the happiest person alive and for another moment I am the sides person in the whole world. Also there are times, when I just hate each and every human being. Then I don't to talk to anyone. All I want to do is sleep despite sleeping for 12 hours at stretch. Most of the time I feel worthless. It seems nobody cares whether I am dead or alive. I don't feel connected to anyone. And from about last 15 days I don't feel like eating anything otherwise I never skipped a meal. I don't know what to do. Please help me out! Sorry for such a long question.
