Need Help

So me and my mom have never been close or even liked each other. She always chooses my younger sister over. Well I'm about to turn 18 and my wants to kick me out of the house as soon as i do bc my sister has bad anxiety and depression and she blames it on me by saying I tell her to kill herself and stuff but I don't. This morning it was particularly bad where my mom snapped and tried to wreck the car and pushing me out multiple times when she was taking me to school. Then when she did drop me off she pushed on the gas but then slammed on the brakes almost hitting me like she was gonna run me over. And I'm afraid that my mom is gonna snap again and try to kill me again. And I would move out but I don't have a job or any money bc she has went through everything in my savings account except for maybe $20 and I don't have any friends or a bf to live with but I can't stay here any longer bc I'm afraid of what will happen. And I certainly don't wanna live with my dad in NY bc he's a shitty father and my life is here in Florida. Please any advice will do bc I'm afraid if this gets worse I might get my suicidal thoughts back again which I tried so hard to push away.
