Daddy's Girl
Sadly, there is not much you can do for him if he doesn't want help. Don't feel guilty about staying away from him when he is drunk. On the anon beards we call that detachment - and it is a good thing.
Keep reading the "sticky" posts at the top of this board and the Nar-Anon board, and start working a program of recovery for yourself. You will need all the strength you can get.
As for your father, I would suggest phone conversations if visiting is too hard...at least with the phone you can cut it short if it is uncomfortable. Just let kim know that you love him and encourage him to get help if he appears receptive.
My prayers go out to both of you.
