Why do I keeping thinking they'll change

Thry treat me like a slave with no feelings. The constantly talk about me behind me back and the go on and make me feel bad for calling them out on it. The only reason I'm still at this goddamn house is because they take all my money each week so I can't find another damn place. If I ask for help I'll lose them all. They make me feel like I'm nothing.... I don't know what to do anymore
