Like you I had a grade 6 TPF (motorcycle accident) and after 15 months in a wheelchair I began to bear weight (Sept 3, 2014). I began to take steps a few days after that, and about 2 weeks after that I started walking.
I hear you when you speak of those dark and sad days. I can still hardly believe the extent and consequences of this injury.
To all visitors of this page, there will be times it seems bleak and unending, but it WILL get better. It just takes some time and lots of rehabbing back.
Keep the faith and hang in strong!
