Help me, please

what shud I do? I have this friend and @ times she can get pretty weird but don't we all, so I don't really mind. its when she makes me look mean and dumb that I feel like I hate her. people ask how does she make you feel mean and dumb I say she makes...

me feel mean because I told her I don't like obama, so because I don't like him she calls me racist and that pisses me off then she makes me feel dumb because she's constantly popping up behind me and it makes me jump, I look stupid because I get scared. she has been home schooled her whole life until now, people think I'm crazy 4 thinking she has very little people skills. she hasn't been around people long enough 2 have any if you ask me. I do feel bad 4 her though because people @ school constantly make fun of her because she likes 2 wear black and lots of it and she's bi. that's another thing evrytime we start talkin about sexuality, she basically crucifies me because I think it is wrong 2 b gay. it's not that I go 2 church, I just don't think it is right. 2day in pe I screamed @ her GET OFF ME.evry1 says I was wrong 2 yell @ her but I don't think she shud've jump up behind me. I cud've cussed @ her or worse beat her up as an impulse. I was her 1st friend in school because we met on the bus and she was my newest friend in a long time since bout 6th grade, I'm in 9th now. I ask of you what do I do before things get outta hand and someone gets really hurt? rough the friendship out or end it. the only problem is if I quit being her friend all my other friends will hate me because they're friends with her 2, plus it will b very hard 2 avoid when she is in all my classes. please HELP ME

Just talk to her about how she makes you feel, she might not realize what she's doing because some people when they do that they don't realize it. Someone needs to step up and tell her what she's doing, it's the only way she'll know.
