Family From Hell

I can't take it anymore, I need someone to talk to. I am 20 years old, single, still a virgin, and living at home with my parents in debt. Me and my Dad fight all the time, he has even threatened to call the cops on me and throw me out on the streets, which I've been to so I'm not that scared of them. He is a horrible human being and he and my mother are functioning alcoholics. I am scared that I'm just going to be out on the streets again without getting a job first to pay off the debt I owe to Arizona State University so that I will at least have a chance to go back to school in the future. I don't want the door to Education closed forever just because I can't pay back a measly $2,679.00
My Dad says that he loves me but he is a drunk, delusional, psychotic person that says one thing and then as soon as I forgive him and start talking to him, he treats me like **** and starts another fight with me. I am not speaking with him at this time but then he gets angry at me for not talking to him. I think he is sick in the head and delusional, because the very next day after a fight he'll be all "Hey how's it going?" Like nothing happened the night before. It makes me want to vomit and scream. I don't know if he is partially schizophrenic or what. The worst thing that could happen to me is that I end up in skid row in Downtown Phoenix, Arizona. But I just want to be able to live here for a couple of months and pay off the debt that I owe so that I can move out and move on with my life and never move back, no matter what. **** it, I will go to the homeless shelters if I ever find myself in a bind again and seek the help that I need to get my life back on track if I ever need to again.
