Oh, ouch! It sounds like you had a classic just starting with clipless pedals crash - unfortunately with a really bad outcome. Hopefully your attachment to the pedals (and use of your new clipless pedals) won't suffer from this once you are able to ride you bike again. And hopefully that will be fairly soon.

It should become second nature for you to unclip (easily). I guess the key when falling is to try not to put an arm out to break the fall - but at least your pedals kept your legs safe.
