I personally don't know. It is a hard call. Either put up with your parents and their drinking and attitude, or move to a place where you're going to have to lock yourself in the bathroom for moment's peace. I know your family wants you, but can you put up with no privacy? Or can you tough it out with your parents?

I know I need privacy at times but I also need less stress. It sounds like you're trading one stressful situation for another. Neither is really helpful in my book.
