I hate them girls at school?

they are full on barbie wannabes, i must admit they are pretty but what do they look like without inches of makeup? i am not a jelous person or nothing but it sometimes annoys me the way the act like ewww and stuff like that. they are quite immature and some are pretty but you can tell they love themselves, walking around school thinking they are it flirting and stuff. ok i try to smile to a few of them loads of times but they just look at me like a piece of sh**t and dont even crack a little smile! soz for my language lol (if any young ones reading this)and i feel really ugly next to them because all the boys look at them and find them "hot" and stuff. help
