Needing someone

I live with my dad who had being very physically and mentally abusive in the past. I moved out to live with my mum after it got really bad and lived with her up until the point a few months ago she moved away with her boyfriend who doesn’t like me. I now live with my dad again and things are steadily getting bad again. Right now he is going off and me and my brother and I’m scared. I’m really not sure what I should do. I don’t have a lot of options as I don’t have the money or support to move out and I don’t know if I would cope moving to a new city to be with my mum. I feel like I’m stuck in a bad situation and honestly don’t know if a way out except suicide which becomes more and more likely
