depression

I'm a 19 yr old girl with recurrent episodes of crying mainly during night or when I'm alone. Sometimes even a small sad thing makes me cry, and sometimes I cry for no reason at all, mostly due to being away from home even when its perfectly clear that there is no other option than staying away from my home.

I'm perfectly OK with the one I love, but I'm sad because of this thing. I have very low self confidence. I used to study but not now. I want to be away from this life and just sit and read novels or paint and draw. I don't socialize with people. Very bad communicator. I have just one friend and a lover in college.
