Annie, it saddens me to hear of your misfortune and I hope you recover fully and quickly. I usually try to find silver linings in stuff that happens to me (well, when I was younger anyway) so maybe now that you have first-hand knowledge that these things can sneak up and bite you might imbue you with a healthy respect that will keep you alive and in good health until claimed by old age. My wife had an altercation with a guard rail under circumstances not totally unlike yours the day BEFORE she took her MSF course. Needless to say she was extremely sore during the training and I got to re-paint her scoot way ahead of schedule!
I remember reading a long time ago (probably when you were just a twinkle...) that most riders had their "crisis" not too long after they convinced themselves they had it all figured out and were the master of the beast. This quite often happens at high speed with often fatal results. My crisis only resulted in bent parts and picking gravel out of my thigh and arse for a couple of days and I remember being really sore when I sobered up.
Get up, dust yourself off, and get back on the beast! At least you don't have good "friends" coming over with all of the funny jokes they can scrounge up in an attempt to make you laugh. I remember how much that hurts...
