I am really really sorry this is happening to you, it must be very very hard. Omg like seriously, nobody deserves to go through this. I don't imagine how I would manage to get out of the situation you're now if I had no place to go. You say there's a chance your mom may accept you in her house if you beg to her, GRAB that chance if you have no other option! Move in with your mother. If that means presenting male, you will have to do it as harsh as it may sound. But survival is top on the list. You need stability, shelter, food, all your basic needs met for you then to start thinking of living your life as you want. But right now you need to SURVIVE this horrible situation you're in that may get worse over time. And after you have more stability in life, you will be able to live as you want without others controlling or holding you back. but right you can't afford to be proud if that means you'll be risking your life and putting yourself in danger. Whatever happens, just know it will get better!
tight hugs and best wishes,
