Sometimes things have to get worse before they can get better. Zen sort of mentioned it. She's got to get pretty miserable before she's going to decide she had enough. (that rock bottom)
And you can't hold yourself responsible for HER reactions. She engages in extremely self-destructive behavior. That's not your fault. She's going to do it whether you invite her or not. Best have her home drinking than spoiling your party.

Please don't feel guilty, that feeds her behavior. Have fun.
