I don't care if your in your dad's face telling him your not going to listen and what a low life piece of crap he is, he has no right to hit you like that, or do any of that stuff to you, yes it's physical abuse. Your father is old enough to know better than that. If he can't control his temper, he needs help. What are you going to do? Do you have a number for social services if you need it? They can put you in an emergency shelter, and get you into a foster care home, or there may be options where they can try to get things worked out with your family. You should at least make the call and see what they can do. Your father seriously deserves to go to jail. Does your mother say you deserve it too or just your siblings?
I've dealt with alot, having my kids put me down, disrespect, one hitting me, having a brick thrown at me, a gun put in my face, helping one get off of drugs, one stopped going to school, cussed at, you name it, I've dealt with it, but I tell you what, I never once layed a finger on either one of them. Both my kids have turned out great, but it wasn't easy getting there. It's tough on a kid if they don't have the love they need from a parent. I hope you don't let your dad's stupidity affect your life. I don't care how your acting up, you don't deserve that. He needs to be acting like the adult. If you are getting out of control, there are plenty of methods he can use to try to make you mind, by beating on you, he's just being a creep.
