First thing is first, is to stop drinking. Second is to focus on yourself. Get your head straight and in time, you family will come along when you are more stable and more reliable in life.
Personal your parents relationship is their issues and not yours. Although your the daughter whatever problems they have is their problem is not yours and fighting them about it, even more being drunk at the time only makes it worst. The only time you should get involve if they someone is physical hurting the other besides that but out. Not trying to be mean or anything.
Hope you feel better soon!
