I agree with Alice Kate....Al Anon! There is alot of great reading material here on this site too. I think the biggest thing to remember is that you didn't Cause it, you can't Control it and you can't Cure it. You can take care of you, your parents can take care of themselves. Alot of times when dealing with alcoholics, we want to take responsibility for them and their actions (codependent behavior). What they do is not our problem, we are responsible to ourselves and how we deal. My alcoholic was my husband. I got a divorce recently. Many, many people are able to stay in close proximity with their Alcoholic and carry on with life. Keep reading, keep posting, get to some meetings. SR saved my sanity.
