I recall the first time I was hurt, a broken back. The injury was bad enough, but worse was all the shit to go through to get better. Being the first major injury, I didn't have reference points to evaluate injury magnitude or recovery time. It scared me.
There was a strong possibility of never again doing any 'action' sports, even street riding. I recall that time vividly, and I was 19 years old at the time. It was bleak, mentally. Had moments when I just wanted to do the final give-up. Since then, well, a broken femur, torn Achilles, 8 ribs, multiple shoulder dislocations, broken foot, kidney surgery, knee surgery. At least for those moments I had points of reference, and although the pain factor was more than the broke back, the mental portion was far easier to handle.
Don, I bring this forward in case this is your first major injury. You will get better, it will improve. It takes time, PT, and mental stamina. You've been the bull all your life; it's not easy to not be strong and able to do pretty much what you want when you want. It's a normal feeling, especially for alpha males.
Hang in there... It WILL get better!
