So very sorry about your daughter. You know, I think one reason why we all go through this, is not just for ourselves and our own lives, but to be better able to help with those who are dear to us. I know one big motivation for me is that my parents are going to need me more and more. I wasn't able to be of much help, with two knees that could barely keep me up. And I'm sure with your daughter, you need that knee, to be of such help to her. Best wishes for you and your family.
