I think this explains a lot of her behavior. My stepmom abuses pain/sleeping pills and I've had to really detach on it. It's hard, but we can't fix them.
Although I know this was nothing you wanted to hear, I'm glad you were there for your dad. It's pretty hard dealing with something like that all by yourself. Just remember...you don't have to DO anything about (actually can't do anything), so keep taking care of you. I hope your dad can take care of him, too.
Hugs and prayers to you and your family!
