My Fault?

After my horse came back from the trainers, it was my job to continue her training and ride her often to further desensitize her to the riding process. One of the days we were out it was very windy and the trees in the paddock we were riding in were rustling about. Gracie, my mare, didn't seem to notice the chaotic disturbance though, and simply plodded along as I made her go in circles around the fenceline. Suddenly, as we passed a large tree and the wind picked up again, Gracie spooked and began bucking wildly. Unable to regain my seat, it didn't take long for me to hit the ground as the horse continued to thrash wildly above me. Her hooves landed on either side of my head and body. One of her hind hooves kicked my leg as she galloped off, flipping me over and ripping my jeans. Thankfully she slowed to a stop once she got to the other side of the paddock, and I was able to capture her before the pain in my leg overwhelmed me. The horse seemed to be as calm as ever after the ordeal, but the shock and pain of my injury has kept me from riding her ever since. I may never know if it was the wind, tree, or simply my lack of balance that set her off on a bucking spree, but whatever the influence, I ended up on the ground, with a nasty kick mark to my thigh, and a nervousness of riding this particular horse.
