Hello juicyxluci, and welcome to our little corner of recovery
A great place for support is your local meeting of al-anon. You can find them in your phone book. They are the experts at living with a family member or parent that is drunk and nasty. They have excellent books and pamphlets with all kinds of helpful suggestions.
Since you are still living with your mom you might want to check out the forum "next door":
Friends and Family of Alcoholics - SoberRecovery : Alcoholism Drug Addiction Help and Information
Take a little time to browse thru the "sticky posts" at the top, there's a lot of great suggestions and wisdom there.
I can't tell you about your Mom, but I know lots and lots of Moms that raised kids all on their own and didn't ever drink over it. One of the things we talk about is how an adult has the _choice_ to start drinking, and the _choice_ to go get help when the drinking gets out of control. It's not like you're chaining her to a dungeon and shoving it down her throat, if you know what I mean.
I'm glad you decided to join us and I hope you post some more.
Mike
