Have that rear wheel checked for true while you're at it. Prolly ok or repairable, but might as well have that info at the same time as you're dealing with the helmet. Also check your gear, lycra's darned expensive to replace. If it's due to the accident you have no reason to feel bad. The driver's made a mistake, not you, and you shouldn't have to pay for that.

Glad you're alive and reasonably well despite being a more colorful character now!
