Get out!!! You can rent a studio apartment for $500 in Philly. I know there's got to be something out there for you. GET OUT NOW!!!!!!!!! You'll be better off. I know it seems scary but trust me-you'll feel a lot better. A WHOLE LOT BETTER!!!
Please, go back and put a down payment on the apartment. Quit making excuses to put up with that b.s.-you deserve better.
