Wow. I hope that you heal up better than new. Falling is no fun. What's worse, it can destroy your confidence, an essential part of good cycling.
While it may have sounded like tough love, I'm going to agree with Tim. Likely cause of your fall was technique-related. The fact that you had navigated that turn many, many times before says that something was different about how you approached it this time...maybe more so than the surface simply being dry and dusty.
