Hi, welcome. You are right the point is to stop drinking but some never do. My dad didn't quit drinking till he was 80. and then only quit because he was thrown in jail for trying to shoot my mom. So you need to think about yourself and how to live happy no matter what she does or doesn't do. Nothing you do is just cause to make her drink, so don't think that. Alcoholic look for, make up, and find excuses to drink whether you are involved or not. It's just who they are. Please try to find an Alateen program near you or get some books like MsPINKAcres said. Focus on you and she will do what she does. She may get better or she may get worse. But you can be happy, I know it sounds impossible but believe me, you can do it. Read through some stickies above and keep posting.
