I'm going to a new school soon?

So I'm transferring from a big public high school (grade 9) to a tiny (22 student) alternative school. I'm transferring out for a few reasons- drugs, kids at my school are very straight-edge, I have ADHD so I have trouble focusing, also I'm more of the alternative type person.. Anyway, I'm either transferring this week or for grade 10. The thing is, I know like one or two people there and I don't want to hang with them because they are way into drugs and I don't want to go back to that scene. Also at this time of the year everyone will already probably have their own cliques there and I might just be pushed to the side because it's only like 1 month of school left and then summer. Help? BTW the 22-student is grades 8-10. Thanks :) Also there are no girls in my grade and I look like a very edgy girly girl (ok, ok...slut. but not SLUTTY. Lots of victoria secret PINK, and that sort of thing). The kind of people I hang with are usually the metal heads/stoners/ravers and they never realize I'm like that too so it's going to be hard I am afraid :/. I don't even know where I'm going with this question, but any advice would be great :)
