Loss of interest, loss of appetite. It.

I seem to have lost all interest in almost all the stuff I do except a few things. I don't like to socialize. I don't socialize. Most the time I'm always at home alone with my computer(I'm learning computer programming). Whenever I'm with people at college I get the feeling that I don't belong.I feel like an alien. This feeling has been there for a few years now but It seems to growing day by day upto the point that I'm writing this answer.It's so hopeless that I'm writing this now>I feel like a looser. Also I've been loosing my hairs for few years now.That sucks! I have even lost my sleep cycle now. Sometimes I wake up in the middle of the night at 2 or 3. can't sleep after it. I feel uneasy most of the time like I'm feeling right now.I just don't want to feel this way! Everything feels meaningless.Everything feels rotten. I have thought about suicide but I have come to know understand that I lack the guts to do even that.
