What a heartbreaking situation for everyone. It sounds to me that you're doing a very good job of handling it, better than I would. You talk to her and you're there for her and these are the two most important things. It might be a good thing for SD to learn about alcoholism, that it's a disease and not her mother being lazy and stupid. Yes, she brought it on herself probably but she doesn't deserve cancer, doesn't deserve to die. She is very, very lucky to have you. God bless....
