Janehill,
Just to let you know, I have raised my 2 daughters single handedly for over 17 years since the death of their father. I have no doubts about being able to depend on them to take take of me if I need it. Afterall, I have taken care of them. We talk about this a lot.
I am currently taking care of my fiancee' who had a massive stroke and is paralyzed completely on his left side. I feed him, I change his diapers, I bathe him, and I cry everynight, because I know I will never be able to leave him. I get very angry sometimes, but I don't blame him. He would never tell you I have ever said or done anything to hurt his feelings. He didn't plan this.
You may resent the suggestion that you try drug therapy if you like, but I stand by it.
