Why am I such a misfit for being a good kid?

I really don't fit in at school at all! All the girls are preppypreppypreppygirlysnobby! I don't want to be like that and I don't think I'm better than everybody else like they do.I feel like such a there because I'm not super girly. Everybody thinks I'm weird for not liking the guys at my school but the guys are just the same preppysnobbyonlyattractivetoprepgirls. I just hate it and my mom thinks I'm weird for not going where everybody is going to be. Like if all the kids in my cl are going skating saturday night all they do is sit on the sidewalk outside the rink and smoke pot! And a lot of people go under the playground and just make out with random people they met 20 minutes ago. One girl in my cl thinks it's funny when people say she is going to be pregnant before she turns 14 because she makes out with OLDER different guys all the time. My parents think I'm trying to exclude myself from them and it's my fault that I don't have friends but they would all be my friend if I smoked with them and drank and dated different guys everyday. Sorry If this isn't a question I just need some advice!
