Pay it forward, become very promiscuous.

I don't think that you can change your personality.
Even if you cover up who you are with being nice, you still are mean deep in. If you keep it all in, eventually you'll snap.

But then again, if you feel sorry for these things then you might have a chance at changing. Just don't kill yourself, that's the coward's way out.

If you were mean "deep within" you wouldn't be concerned about wronging others, let alone feel bad about it. You can start bettering yourself by going out of your way for others - I know that sounds like lame advice, but the good it does is that you start to feel good about yourself and your place in the world when other people benefit from you. Don't let them take advantage of you of course, but make an effort to brighten someone's day when an opportunity comes up. If need be, you may also want to talk to a counselor about the bullying that put you in this position, I know that's a hard thing to get through.
