What's wrong with me?

Hi, I don't have anyone to talk to so I went looking around and found this board; but let me get to the point. I think something is wrong with me.. I'll describe: I have absolutely no friends.. I can remember when the same people who make it hell for me now were my so-called "friend" and now we remain persby and I see them as the enemy. No one wants to talk to me I am a loner. I've been in too many fights and can't see myself going to jail again. When I see others having fun, talking, laughing and kissing on their little girlfriends or boyfriends I get enraged like I want to wipe everything out. To make this story short.. I think what is best for me is to commit suicide I am way too sick of having to wake up everyday with people treating me like total CRAP. I have dreams on almost a nightly basis of payback before I do the deed to those who talk, stare, and play with my mind. There is VERY strong doubt of me living this through.
