What should I do about this father?

if you really mean that, then leave the house. you are 19, so you can legally go where you wish. if you can't pay for a place on your own look into sharing a condo with some other people your age and rooming with them, as long as you get along and they aren't bad kids cause that could be a terrible situation to put yourself into. if your dad follows you and is over-stepping boundaries then you can get a restraining order.

i'm really sorry for you! :(

Be better than him

and be nic to him first because he is your father, even if he is the worst but you are being better and doing what a daughter should do maybe one day he will know that be was wrong to you and appreciate you for being a wonderful daughter.

2nd i don't know you of course but ask you self why is he treating you bad be fair when you are answering this question, cause the answer will show you the problem and finally if there is any chance that you can talk with him and learn why is he me-en to you that would be even greater

and if you don't feel there is hope that he changes don't worry you are about to graduate and have your own life and family wishing you all the best

How abusive is he, if he punches you or throw you down so hard on the ground than you could call the police as long as you don't hit him. But if you think your not getting the proper treating you need than go to a therapist. If he touches you runaway and call the police to a trusted friend. I can't do much, I am very sorry...

If it is physical abuse, call the police.

If you realy want to get away from him that bad, then leave. Sence you are 19 you probably have a job, maybe stay with a friend, maybe your mom if your parents are divorced.

Well, do you have your mom? Just cut ties with your dad like I did mine. My dad's an achololic and smokes. Constantly in the bar. My mom and I left him cause we couldn't take it anymore.

don't let it get to you he will need you in the end and what you do at that time is on you
