Dear Heartbroken,
When I initially read your post, I wasn't sure what to make of it. I am in the starting blocks at this marathon (still mobile & self sufficient) but I am absolutely thrilled that my husband now works at home, at great inconvenience to himself and his colleagues, several afternoons per week. He does this to keep me company thus ensuring that I'm not alone with my thoughts.
Then I realized, there is something you can do, from home, which would benefit ALL of us. Have you thought of organizing unique fundraising events? You appear to be an energetic and motivated person. You write beautifully and I suspect you are a gifted communicator (if given a chance). You could be our voice in New Mexico and beyond. While you would not be doing one on one personal care, fundraising and awareness campaigns would benefit thousands, including your dear wife and yourself. Plus you can do much of the legwork in the comfort of your Lazy-boy.
Maybe, just maybe, funds raised would lead to a cure and shut down this site!
