Yea, school is a pain. I know how you feel, i wish i could have some awsome job and make a bunch of money and spend it on cars and other things instead of being stuck in school. But all the fancy cars in the world arent worth missing an education. Im sure one day your going to get married, have kids, buy a house and all that other shit you do when you grow up. And when that happens whats a fancy car going to do for you then?
I wouldnt worry about moving away, a lot of people will move away to, you just have to learn how to keep in touch with everyone, and youll make friends whereever you go im sure. And you can always come back to see family and stuff when you want. Hell, you might move somewhere you end up liking more then pittsburgh.
So in the end, just stick it out. School will be done in no time.
