I know at least the physical sensation you experienced, if not the emotional one. A couple of years ago I was just getting back into riding after a 20 year hiatus. My skills were beyond rusty, and when it happened it was late in the ride and I was a little cooked - I tried to hop a curb cut - not a full curb, just like a parking lot entry apron - to get out of some bad traffic. I didn't even clear that stupid little 1" of concrete. I was down before I knew what was happening.
Come to think of it, failing a one inch jump is pretty embarassing after all.
