What to do if I feel like screaming at my friends ALL the time?

I guess I'm very intelligent, so I find the people around me very slow. I go to a school where the majority of guys are 'antisocial youths' and a lot of the girls are complete sluts.
The people around me are sooo shallow and ignorant, and a lot of them bully the emo kids and vegetarians, basically anyone who's not exactly like them (this includes me). I've attempted to talk sense into them, but this has only resulted in a couple of scraps with boys and my bad reputation. =P
I feel frustrated that there's no one close to talk to about issues more important than what boys we fancy. The truth is I'm very bored, and I feel like screaming on a day-to-day basis. Any advice on this?
The thing is I tend to stay quiet because I can't gossip. But this isn't the real me...
