Excuses To Change My Homeroom ?

So I'm in eighth grade and I just got my homeroom teacher.. I don't like ANYONE in it. Now please don't go on about how I'm in school to learn, not socialize. I understand that completely. Matter of fact, I'm in all advanced cles, but I do believe I should have some friends. And another thing, please don't tell me I'll make new friends with those people. I know every single person in the homeroom (I'm a pretty social person) and we all don't get along. Nothing has happened between us, but we're just not good friends and I seriously doubt we will ever be. The point is, I need a good excuse. ALSO, the teacher I got knows me from when I was in seventh and she didn't like me very much.. I'm not sure if she'll hold that against me or not. Thank youu ! (:
