Please Help, We Don’t Know What To Do Anymore…. I’m Scared For My Mom And Sister.

My dad won’t get a job. He’s has bipolar disorder, recently diagnosed with anosognosia, is abusive, anger problems, depression episodes, he’s a narcissist, controlling, a danger to himself and others, and full of himself. me, my bf, mom, and sister have been all paying the bills. Today this morning me and my bf needed to use one of my dad’s cars (my dad controls the cars over us because they are the only ones we have currently to get to work, etc) but his car was low on coolant. We opened the hood and checked to see what kind of coolant it needed. We couldn’t even get the cap to open, it was like it was welded shut. When my mom woke my dad up to ask if he could open the cap, he screamed at her thinking we already put the wrong coolant in. We didn’t even put it in yet, because we know we need a certain one. He threatened to kick me and my bf out, even thought we pay bills for the house. He doesn’t, like I said, he doesn’t have a job nor will get one, he’s planning on trying to get disability. This whole thing started a violent argument. My dad called the police on me and my bf and got him kicked out. After my bf left, my dad said he’s banned permanently, now we have one less person helping with bills. Honestly, now I don’t think we can afford it because of his decision. My dad is gonna take me off the car insurance (I don’t really care because I’m not allowed to drive the car anyway) and I won’t be able to drive to work because he is the one with the cars rn. This man is affecting our lives and we can’t do anything about it. We went to court because of his deterring mental health and to get diagnosed. But he got that whole thing appealed. My mom can’t get grounds in divorce in SC, she already spent 500 on advice, to only be told the same thing. I don’t think I can live here much longer, even thought I don’t wanna leave my mom or sister behind. I can’t stand this piece of shit much longer. Me, my mom, and my sister are exhausted and helpless with dealing with this man for over 23 years I’ve been alive. The only thing we can do is run away from him, but it sucks to see my mom’s house go.
