Hi Kelly
I really feel for you. i have a friend who is handicapped and I know how hard it is to help him only for a short time. I cant begin to think how you get the strength to do it 24/7.
It takes a lot of love to continue to do that and I am guessing that you have a huge amount of love in your heart and I am sure that it is very much appreciated even if the appreciation is not always visible.
Hope this helps.
Sam
