How to survive High School as an outcast?

I'm 16 years old, and i'm a guy, i'm just very confused about school. I go to a school in los angeles, that consists of a whole lot of valleygirls, cholo's, and skaters. I am a COMPLETE outcast. I can't relate to anyone in my cles, or anywhere for that matter. I am a quiet person, but still personable. Whenever I am in cl, I am either reading, writng, or drawing, and everyone just looks at me like I'm insane. I get real good grades, so I guess i'm lame cause I have intelligence. A big thing in this school is that being a failure and illiterate is "trendy". And it's not that i'm ugly or anything, not to be arrogant or y here, but I am known to be an attractive person. How in the hell do I go through high school as an outcast?
