How do i forget about those bitches? i know its long but please help...?

ok so i'm in the 11th grade and i have 2 best friend who've been my friends since the 7th grade we were so close, so much so that we called ourselves 'SMQ'. ok so in the 8th grade 'S' made some more friends and we sort of became a clique. but the problem is that i can't stand those girls, they're so ghetto. i hate the way they behave they're loud and one of them curses so much it's sickening. i know this sounds shallow but they're also very ugly both inside and out. i don't like to be seen with them and wat makes it worse is that my best friend has started to behave like them. its disgusting. they constantly disrespect not only each other but other people in the cl just to make themselves feel better cuz they're so ugly. i hate to make others feel bad and i just hate swearing so much. on facebook they put disturbing comments under my pics and they think its funny., ITS NOT. one of the girls has stopped talking to me because my aunt told her off when she made a rude comment on fb. so stupid. therefore her closest friend in the group has stopped talking to me as well. that's another thing, they aren't independent thinkers. my seat is beside the one who has stopped talking to me and whenever we have home room she sits in her seat and waits there until i show up and sit down so she can get up and go to another seat. this is so stupid and what annoys me even more is that her friend ( the swearing one) just laughs and laughs. i don't eat lunch with them anymore but i know they talk about me a lot and whenever i walk buy they make comments like 'ew!' or they justlaughf and laugh. we had good times yes but more bad times. they always make everyone they think is better than them feel like ****. for example, 'M' has always had nice stuff. she lives in a upscale community and hangs out with upper cl kids at school. but her best friend, 'S' has a whole different group of friends so to maintain the friendship she tries to fit in with them. they tell her that she smells and looks weird and all kinds of stuff. she has depression problems in addition to many more problems because a teacher accused her of having gay feelings towards her and it doesn't help that they criticize her every second of everyday. and now she kisses their s so much just so she can fit in. its so sad. and she's not the only one. they did it to another girl and now she's not talking to me because i told her that its stupid to try to be something that she's not just so she can fit in. now that 3 out of the 6 aren't speaking to me, they make it seem like they're so happy. laugh so loud that i can hear them when i'm eating lunch a mile away. they go to pizza hut now, which they never do, and they give each other gifts, which has never ever ever happened before. i've made a whole new set of friends and they're great, but the problem is that they're soooooooo boring. the one thing about my other 'friends' that i liked was that they were funny. 'S' was always the one to make jokes and she's super funny. i've never been so bored at school. i have to make all the jokes and that tiring. i love my new friends i just wish they were funny they are, sort of but not really. what do i do? how do i forget about those girls? how do i not make them bug me? help me please! they make me not want to go to school
