Healing Emotional and Verbal Abuse

I am 16 years old male who grew up in a household with a bipolar alcoholic father. He left when I was 12 but he would come back some nights to scream at me and my mother and then I ended up in and out of mental hospitals for a time for wanting to take my own life at age 13 but I have made a great recovery over the past years but recently my father has been sending me abusive messages and he says that our relationship is over but I feel there is still hope so how do I go about dealing with him while I try to further my own recovery?
