@RexDraconis111,
I just discovered this thread; so, I'm a latecomer. Since some good advice has already been given, there's not much to be said at this point. I'll probably end up sounding dumb.
I'm very sorry for the trouble you've been having. Don't blame yourself for what's happened. Bullying is evidence of flawed character. In a sense, the bully is the one who has a problem, not you.
IMHO you need to make a distinction between self-defense and getting even. Think of the people you know who believe in the "getting even" philosophy. Generally, they're not the most pleasant people to be around. Repaying evil for evil doesn't work very well.
In the situation of physical bullying, when a bullied kid eventually fights back after other strategies have failed, this is self-defense, not getting even. There is absolutely nothing wrong with self-defense. Over several years I've read a lot of posts in various forums from guys who say they were physically bullied when they were kids. Fighting back seems to work in most instances of physical bullying, even if the bullied kid loses the fight. At least the bully knows the kid will fight back. But this is not your situation.
Regarding cyber-bullying, I think the best course of action is just to leave the forum where it's taking place. I understand your feelings of frustration, but this is the one situation in which the advice "Just ignore him" seems to be the best strategy. Messing with jerks online is just a waste of time. I'm convinced very little can be accomplished by trying to get back at someone online.
In the meantime, try to give yourself some emotional relief. I know this is hard to do, but evict the jerks from your thoughts. They're not worth your time or consideration. Rediscover your own worth as an individual. Think of a way you can be of service to others. Perhaps you could learn how to counsel bullied kids in some capacity.
Sorry if this sounds trite.
