What am i to do?!?!? MAJOR HELP?!?!??!?!?!??!?!?

If they do any of those things, tell a camp counselor, or whatever adult is around. If those girls are treating you so badly, they'll probably allow you to move into another cabin. You can make other friends at the camp. I'm sure there'll be some girls who didn't bring any friends either. I hope everything works out well, and even if it doesn't, the week will end. I hope you end up having a good time :)
