Ouch!
I can never understand the crowd that insists that helmets don't make a difference. I've only had 3 spills in over 20 years of adult cycling so I consider myself pretty lucky. Hope you heal quickly.
P.S. - don't be surprised if you are a bit skiddish when you get back on the bike. I understand there are some in the pro pelton who have never gotten over bad crashes and, consequently, are considered bad decenders.
