No matter how good you are, how good your bike is or how good conditions are things like this will happen. My first few times dropping the bike didn't affect me much, but last year when I broke my shoulder definitely got me.
What most people will probably say is just keep going. The truth is once you know what it's like to go down you'll never un-know it, but if you do your best to just carry right on I think the trauma will be lessened.
I had to wear a sling 24/7 for two months after I broke my shoulder, but the instant I could lift my hand to the throttle I was out again. I'm glad I did because I recovered just fine and if I hadn't just gotten right back in the saddle I may never have ridden again.
