Just wanted to add another voice of support. I've had my share of falls, but fell off my current lease mare for the first time on Monday; she spooked, shot off to the left, and I fell straight down as though the rug had been ripped out from under me. My trainer was in the arena lunging her horse at the time, but apparently didn't see the fall. She turned around and saw me on the mounting block getting back on, and was like, "What happened?" I told her I fell, and she said, "how did I miss that, it was all so quiet" :) After I rode a few times past the scary spot, I got off, and she called over to me, (jokingly) "did you dismount this time?!"
Anyway, good for you for getting back on. And glad you're no worse for the experience.
