Girls help. Girls...help me!?

Um...hi. I'm just entering this school-middle school- and almost every girl there seems flawless. They dress like prostitutes-no offence, really! and well...they're kind of popular...and mean. People like that is what makes you struggle through school, and what I'm saying is that I need help-from girls who have survived middle school-and are livin' the good life. Any tips-beauty tips, avoiding bullies-any will be apreciated. Please help me! oh yeah, I don't want any pores, pimples, acne...any tips of how to avoid those evil nasties?
