I think that once you are healed you will want to ride again and you should. I know from my own experience of getting bucked off of a horse on a trail ride. Did something spook the horse? Were you riding in an arena? What I did was start out in the ring with this same horse and got my confidence back and even got to riding him at a canter without stirrups! It may help you get your confidence back if you start out with a different horse, like a calmer, older horse until you feel ready to get back on the same one again. You can do it!

By the way is this your horse, or your friends or a lesson horse? Can you give more background about the horse and what happened to make you fall off?
