Jeez... what a *****. Sorry to hear that.
Lots of people have compensated for injuries by assiduous exercise programs, and no doubt you will too. As one who's suffered permanent nerve damage, I can tell you that it's difficult. You'd think you could just strengthen what's still working to make up for your losses, but it won't quite work that way.
Still, in a few years, you'll be in better shape and your friends will be in worse shape, so you'll be back at least to par...
