Unfortunately there's nothing you can do about your father's drinking. That part is out of your hands. What you can do is set the boundaries you need to in order to be healthy and at peace in the meantime. Often times that means detaching with love and recognizing that we can't control someone else's choices, and we aren't responsible for the consequence of those choices. They are. When we realize this, we don't fall for all the drunken self pity and woe is me my life is so awful bologna that alcoholics like to dump on their loved ones. It's not harsh. It's removing ourselves from their vortex of chaos. You have a right to love your dad from a distance and not have your life held hostage to his alcoholism.
