Have you told the teacher or you're parents? I mean, I would really like you NOT to run away or commit Self Delete, seriously.
I've heard way to much about people commiting Self Delete, and I'm not gonna do it, no matter what.
If some people bully me, and I tell me parents but they don't do anything, I'm gonna loving kill (not really :D) my parents or teachers.
EDIT: If you want to be violent, then just kick any of the bullies in they're nuts, vagina, richard, balls, whatever.
Anyways, ya, do what I said.
