I was facing a similar prospect about 35 years ago I feel for you cos it scared the crap outta me. It didn't come to that, however, and hopefully your situation will have a similar result. I'm fortunate to still have both my legs, so I'm praying that miracle will also come your way.
It's great to see you with such a positive & strong attitude, and sometimes that's half the battle won. Take care, Nimbin, the wife & I are thinking of you and hope for the best possible outcome possible for you.
