I am convinced that, as we say over here in America, you'll feel better, and have a better relationship with your parents when you "get yourself out of Dodge City", get on your own, work on your sobriety, your most valuable possession. Your AV probably feeds on your resentment, to try to encourage you to drink. Don't fall for that! Get off on your own. You'll be less "passive", more self reliant, and your parents will be less controlling enablers. In that respect alcoholism has been rightly called a family disease. Even when the parents are not alcoholic they can very well be toxic.
