I wish you and Cindy well on your journey back to good (or at least better) health. I would have wished you luck but you and everyone else know that luck has nothing to do with it. Keep your head about you, you'll get where you're going. Listen to your doctors and return to physical activity when you are able to do so. In the mean time do whatever you can to improve your situation, no matter how small it is...it all adds up.
Take care,
Bau
