After a few years being schooled online, i have to return to public school, where i spent time being ignored, bullied horribly, physically and emotionally, was called ugly, etc. i'm going back, and i need to know how to be popular, what should i wear, how should i act? ?

I'm sorry you were treated badly but becoming 'popular' won't do anything but turn you into the exact monsters that hurt you, or at the very least you'll be surrounded by 'popular students' that treat others like absolute dirt. If you want to act popular, start shopping at the most expensive clothing store you can find and start acting snobby, talking down to others, because that's what popularity in school is about about these days. You'll gain a lot of rude 'friends' and you probably won't be bullied, unless they decided to use you, but you'll watch others get the same thing you used to get instead. Good luck!
