Sue, I've been following this thread for a while now, and I can't even begin to imagine the emotions of getting back on after such an accident. However, you did get back in the saddle and should be applauded for that.
From your comments about keeping the mind really busy helping, why not go back to your initial plan and do some of the trials bike riding to get the basic skills going again? Having dabbled in trials a few decades ago, I can attest that it takes extraordinary concentration to do it well, and that may have some very positive reinforcement.
