My father is a really bad alcoholic that abuses me, my family,and has disgusting behaviors

My father is almost 60 and he’s out of control. No type of therapy helps him. My mom just works and works supporting him with only one income. However, she doesn’t really support him and it’s just for him to get by with food like taking him to the grocery store in her car. There marriage isn’t even good because she’s constantly fighting with him as soon as she comes home from work. This has been going on for over a decade. My whole childhood they have been fighting actually. The past 5 years have been even worse. My father will constantly call the police to our home because of stupid arguments that we get into. He will try to get me arrested because I call him names, but the fact is that he does so himself at first and harasses me and everyone around him. The police come and do nothing and just leave. This year the police has came to our house at least 50 times. My father has disgusting behaviors such as contracting an STD many years ago from who knows and hiding it from us. This has severely declined him mentally. My father got into a DUI accident in the past and tried driving away from the scene of the accident. He drove all the way to our house while being followed by the other driver and was arrested here. He was hammered and telling me to park his car on the driveway for him so he doesn’t get caught, which I didn’t. My father has been seen passed out on the floor outside many times lying in his own urine. He is constantly dirty, has torn clothes, and walks around the house smelling like urine. The other day he purposefully let the dog escape because he wants to piss me off on purpose. Every time he gets admitted to the hospital they just send him right back home. I am not involved with my father’s care because we don’t get along due to his behavior and how he treats me. My family has no visitors because of his behavior and we are so out of touch with all of our family despite having many members. I have reached out to them many times about this, but they’re no help. Our neighbors look at us funny because of our deteriorating house condition and the history of constant police coming here. I am successful in my career and support myself, but all this is taking a toll on my mental health including my siblings. My mother doesn’t want to leave him despite the fact she says she will many times. She will just yell at him and threaten him to leave. I am concerned about my mother because she’s only getting older and eventually she will have to stop working. She is literally working herself to death and sometimes sleeps in her car because my dad keeps harassing her when she comes home from her two jobs. My mother doesn’t get a full 8 hours of sleep either. I wish there was a way for you guys to truly grasp how dire my family situation is and my dad alcohol and mental situation. What can be done?
