I think that I am severely depressed. Every night I cry because I think I am a worthless waste of space. I used to love hanging out with my friends but I never want to anymore; in fact I have gone out of my way to avoid social contact, and my mother has noticed this. I have had serious thoughts of suicide. I have also gained weight lately. I am only 14, and I am afraid that my parents won't believe me if I tell them. Am I depressed, how can I tell them if I am? Please help me.
