I don't know what to do anymore?

You need to find someway somehow to get out of your living situation. Unfortunately until you do, you are going to have someone trying to bring you down. It sounds like she is doing a good job at it. If you work, try finding a room to rent instead of an apartment by yourself. Look in the classifieds, they usually have people needing roommates and it is far cheaper than renting a place on your own.
