I am very impressed with your search and congratulate you on your efforts. I believe, by your personal determination to continue to try to find the right solution you will be successful. If it helps at all, I did some research a while back so I could help my mother, who has had MS for over 25 years and is now so poorly, unfortunately that she has regular care and I have no power to help her, despite my experience and knowledge. I have learned people can not be helped unless they want to be.
