I need help with school stuff?

Ok so last year there was this girl I used to be friends with who was soooo popular. Then my other friend moved back and the first one started being extremely mean to me so now I don't like her. She took away all my friends at school exept for one who doesn't like me anymore. I'm going out of town the week before school starts which is when meet the teacher is so I won't even no who's in my class and who my teacher are until the first day of school. What should I do? It's gotten so bad I've thought about moving because that girl has done everything she can to make my life miserable. I don't even no what I did to make her hate me. :-( Please no rude comments only mature ones. btw on the community guidelines it says no venting thats not what I'm doing I just don't know what to do about this

Ignore her and don't let her get to you. That's all she wants, is for you to get upset by what she is doing. I don't know how old you are, but I'm sure you can find plenty of other people to become friends with. I've been in a situation like that before, and I know how hard it can be. You have to keep your head up, and remember that you are a million times better than them and that they are not worth your pain or frustration. Just go into class on the first day and worry about you, don't worry about other's or what they think of you. Life is too short to be anything but happy.

I think you should talk to her and work things out. Everyone can be friends. I think its dumb when someone doesnt like one person and then everyone else doesnt like them anymore. Talk to the person. Dont be afraid. Or make new friends. If there gonna do that to you then there not your real friends. Theres always gonna be someone wanting to be your friend(:
