That is so horrible. I don't know how people can live their lives like that. You sound like you're loaded with stress. I have a friend who's brother, he's 55, can't even go grocery shopping by himself. She has to do it. And her husband won't help around the house or with him. It's really frustrating. I hope things get easier on you. Your sister ought to be ashamed of herself. I don't know how you're doing it all.
