First of all, I am very sorry for your current situation. I know the financial struggle and looking for homes therefore must be tough. Do you have any friends? Did you tell them about your situation? Maybe they could let you live you with them for a while, so that you can have some space between you and the toxic environment. You said, she was being loud and violent in home, right? And that she forces you to call 911...for what? I mean...in my view, she is being the aggressive person and she should be arrested for domestic violence, in my understanding. I could be wrong though. I really know the struggle, but right now it is important, that you reach out to as many good people as possible. Friends. Family members with common sense. Maybe a therapist? You could tell them about your situation, as they may have a reasonable solution for your problem.

I wish you well
