Damn, Homie. Its a hard-knock life, yo. Bullying is just a part of life - an unnecessary and ugly one, but still part of it nonetheless. Feel me? Its a tough situation, and, to be honest with you, there isn't much you can do about it. I guess Im kinda lucky with my friends because we ride together and will die together (no cliche).. So my advice would be to stick close with them, and try and stay out of the way of the punks... go to a quiet area or something, PC Room, whatnot... somewhere where you'll be kinda by yourselves OR go out around the town, chances are you'll not meet up.
But yea, stay up dude... stay strong.
