How to regain confidence?

Alright guys, here's the story. About 2 weeks ago, I was racing dirt bikes in the desert, I'm doing great, leading my cl, then BOOM. I hit a rock and flip, which knocks me out cold. By the time I wake up, I have no clue where I'm at. No idea at all. So, today we ran down Vantage to do some trail riding. Well, it was the first time i've ridden since the crash. and I felt good until we got into a real whoopy, rocky section of the track. I had to slow down immensely to get inside my comfort zone, and that's not normal for me. So, I have a few races coming up, and need some tips to help boost my confidence through the rocky sections. Any help is greaty appreciated!
