How can I come to terms that people are just gonna be weird and different?

I hate everyone who isnt like me, i come from a backwoods family who has had to work there *** off everything we have, i attend a school full of rich kids, emo kids, niggres, white kids who think there niggres, s. I just dont get it, every teenager thinks they have problems. they dont know what problems are. theres this one kid who im inches away from clocking in the face. Hes 17 and dates 14 year olds and has this new girlfriend from a different school who looks like a caveman. all his facebook statuses are about how much he loves her and cant wait to see her. they met like 3 weeks ago. For some reason rich girls are really attracted to me. and it seems to me that the rich girls are the ones who have legitimate family issues. ie moms who married rich abusive douchey lawyers. And the emo kids i just dont ******* get it, grow some and quit crying. I know the emo thing is a new trend but i really have no clue where these kids are gonna fit into in the real world. you cant shovel hay or go to the office wearing skinny jeans and makeup. christ. and to the niggres show some goddamn respect for people and they might not hate you as much. i just dont get it. im pretty much alone i tend to hang around the athletic types because i play football in the fall and alot of those guys know what there doing. i just dont get it. when do kids grow up?
