OP, I know the feeling! I had had
My new horse for about 3 months when a lapse in judgement led me to bail: I had runkeeper going on my phone to map my trails, and stopped him to take a peek at it. He's always been a calm, unflappable horse (or do I though.) but when the neighbor's mare just on the other side of a bank "blew" he spooked and took off running for the highway. I did not have the reins in my hands, and couldn't gather them up. Finally I bailed because I figured that was a better option than getting run into the road. Luckily he and the dog decided they wanted to remain in the field instead of going into the road. I landed on my head, neck, hip, butt, everything all at once and slid for a good 15 feet.
The next time I went to ride, I stayed in our ring and was very tense. I was afraid I had lost the confidence I had had pre accident, and in a way I did. It took riding out in the fields for me to regain my confidence (I still get off and walk past the place he spooked) I am not nearly to the level I was, and I am much more aware of my surroundings, but I am again out enjoying the trails with my horse! I have also realized that riding in the company of more experienced riders helps to quell my fears, and their confidence rubs off on me. I wish you the best of luck and I hope you can find a way to overcome those demons!
