Is it okay to stop talking to your father if he always releases his anger on you?

I love my father but I am tired of him releasing his anger on me all the time. He has anger issues and it has become endless struggle for me. I was born sick but I could handle him better in the past but now my illness has become worse but he keeps on releasing his anger on me. If i have to sleep in hospital then he comes to visit me like an angel and become super caring. Then I get better, then we go through all of it again and again. I swear if my health is better I will just handle him like before and let him feel good after he releases his anger towards the world on me. But now i can hardly stand on my feet. I am young but very very sick.


My problem is that I always feel guilty when I stop talking to him. and he is good at making me feel this way. I didn't talk to him for awhile now and my sister text me saying that he says he wish that I just write him "Hi". The problem is what comes after "Hi" for me is like living hell.

Sorry for my bad english, I hope it is clear enough.
