my car is doing that thing where it SQUEEKS when i drive! ahhh how do i stop it? i think it started cuz i ran outta gas at the top of a hill and had to put on all the brakes and then i maneuvered it backwards down the hill with the p brake on and was generally abusive to the brakes...HOW DO I FIX IT?

You mean the loud squeal when you press on the gas, but goes away later?

Probably the alternator belt is loose, or your battery is getting drained when you park (or battery is dying). A loose belt or bad battery will cause the belt to slip or strain and create a loud squeal.
