Oh dooky, so sorry about your fall. I have no better advice than what you've already been given here, just know that we've all been there (i'm a newbie), as you will discover if you do a search on "clipless" and "falls" or some such! Only antidote is practice, other than the key issue of how tight your clips are. I had a couple of ugly pavement incidents until I had the LBS loosen the tension on my pedals so I could get in and out with more ease. After that, it was a cinch. Keep at it!
