The main thing is that your face, your bike and your jersey are in one piece; and that the helmet did its job. So did the collar-bone actually. That is what it's there for - to break instead of having your neck broken and/or shoulder ruined. Lucky it wasn't far worse. Well done the ambulance too.

You will be fine in no time.
Rest , eat chocolate and ice cream, check out the TE forums. Then have a little nap. Repeat for at least a week.
Then you can maybe go shopping for a helmet!

Thinking of ya!
