I echo what Daffodil said in her post above. If your mother is in denial about her drinking problem, talking to her may get you nowhere. But if talking to her about it will get things outside of you and off your chest, then do it for you.
Next, seek help wherever you can get it. From a counselor, from Alanon meetings, or here on this board. It's obvious that your mother has a problem. But she is the only one who can choose to do something about that.
You can do something to take care of you and how all this is affecting you. This is all overwhelming and scary when it first rears it's ugly head. There is hope, there is help. One day at a time, things can get better.
I will say a prayer for you and for you mother. Most of the time, God is the only one can help. That is why I believe in the power of prayer.
Keep the faith and
Peace,
Gabe
