Well Muffz, after reading this thread you should have a pretty good idea of what High School will be like. For the next four years you are going to be more miserable than you ever imagined possible. Unfortunately for you, you are a teenage girl. There will be lots of High School drama for you, and you are going to overreact over all of it, making yourself ten times more miserable than you should be. You are going to get into fights with your friends, and are probably going to hate every single one of them by the time you graduate. You will cry yourself to sleep every single night for four years straight.
There is only one way out:
Seriously though, you are a stupid kid and you will react to things in stupid ways. That's just the way things are. Work hard, but don't take yourself or anything that happens too seriously, and you will be fine.
