Please help, big problems with my family?

I got into an argument with my mom last night and I cussed, but not at her. I told her at the end that none of those were directed towards her. she went and told my dad I cussed at her. so I come home and he says "heard you were arguing with your mom" I said "yes we had a little argument" he said "and you cussed?" I was honest and said "yeah I did" and here is where it gets bad. he said "I really want to punch you right now. im shaking, that's how bad I want to hit you. come on, put your crap down and do something so I pop you. you know you're a miserable person to be around." then he went on to call me a whiny b. i. t. c. h. i have to move with these people I call parents and live with them for another year. im only 17. they are uprooting me from all the people I love and making me start senior year at al new school all because I have a girl that im in love with who is 19. she likes me too. after all the stress from my family screaming at me and threatening me for the past six months, I want to just end it. the only reason im even typing this is because the 12 gauge in my closet doesn't have any shells left. I don't even want help with my family because im done with them. after at least the last 5 years of verbal abuse, I hate them. I don't regret saying any of this. if I am to live through this, I will never talk to them again.
