I had (my one and only) Wreck in 2007, T-boned a car at 40mph, strait into the drivers door. Bought a bike the day I got out of hospital, the 90 mile ride home was one of the scariest things I have ever done. I felt every car was about to pull out in front of me. I was shaking like a leaf when I got home. Took months to lose that rampant fear. I still retain 20% of it for good measure.
Don't be surprised.
