I don't know what to do ?

[Why am i so weird]

Hey, i've been in this situation and let me tell you it needs to be stopped early or it will get worse. You dont sound like a bitch to me you just sound like a girl who wants this to stop and wants an answer to why she is doing this. Try and confront her about it, but if that doesnt work try talking to your friends again. I know you probably feel alone and that no one will believe you or people will take her side but this girl is a bully and needs to be stopped. someone will listen eventually. Things will get better and the best advice i can give you is to stick up for yourself, i wish i had done this when i was younger and maybe it would have stopped earlier.

Good luck and i really hope things end up ok
