Hey Jenn,
Step back and look at the big picture- no concussion, no broken bones or cracked skull, didn't get RUN OVER by the car that turned in front of you. Bike is ok too. I'd say you were pretty lucky- this time.
You'll probably be on your bike again in a couple of weeks!

Good that you went and had your wounds cleaned by the pros, and good that you had more xrays just to be sure they hadn't missed anything.
