I need help, please

I'm an 18 year old female and yesterday me and my dad got into an argument because he hit my dogs head with a door and screamed at her, and I defended her and he threatened me and started yelling at me and blah blah blah, and said he was gonna have my phone turned off but hasnt done it yet and he told me I had to move out or else hes gonna be the one that leaves and he left and he told me the final decision is that I either have to move out by March 1st or pay him $350 rent a month, and I don't have a job and I have physical problems so I can't get a physical job without making my problems worse or excruciating, and I don't have a drivers license and I have to take care of my dog and be at home with her because im worried he'd kill her when I'm not home because he killed animals for fun and I don't want him to harm her, and I need an online job but need advice for what ones I should take, but one things for certain I will move out by March 1st and cut contact with him but I'm broke and have no job and I did have a job when I was 16 but he entered his email for my job so he got everything and every notification and then he manipulated me to quit it so now I'm jobless and broke and if I don't get money then homeless with my dog, and he is denying every abuse he's done to me and saying "he's a man of God" and "would never do such a thing" what do i do? I need help I dunno what to do, but my mom's on my side, and there's so much more to this but this is the kinda sum up even though it's long, so, what do I do?
