Crashing sucks. What else is there to say. But now that you have that out of the way, get back out on the bike and you will find that you are now a much better rider. I've been down a few times (fortunately nothing severe) and found that each time I had gotten careless and wasn't really thinking about what I was doing. So at the end of the day, this may be a good experience - at least that's what I tell myself.
