lbw0912 I feel for you. I too was badly injured(not as severely as you though) trying a horse after not having one for 26 years. I still bought a horse two months later and spent the next 4 years getting over my fears that the running/bucking idiot horse caused.
My first horse was gentle and non spooky but I was anything but. Everything spooked ME and that was very upsetting as I used to ride bareback as a teenager all over the place on my mare - at all kinds of speeds
I was trail riding with large groups of people with all kinds of horses - some well behaved - some not. Up and down hills, through creeks, over trees and a lot of time with my heart up in my throat.
I no longer have my first horse, Red. I now have Biscuit and Biscuit isn't spooky either. I don't know if I could have regained my confidence on a horse that was spooking and looking for boogers because I saw enough of them all by myself. I really wish that I had not bought a horse when I did and had taken some riding lessons til my confidence came back and I felt ready and confident like I did when I was a teenager.
I am so sorry you are having these issues. I can't see Jet's picture and I am sure he is a lovely boy but he may not be the horse for you at this moment. Even though Red wasn't spooky he wasn't an old seasoned trail horse either. He was actually an off the track quarter horse but I can say those ottqh's have seen dang near everything that clangs, makes noise, blows up, moves fast or unexpectedly. It was me that had the problem but had I been on a horse that had a problem too, would have been my downfall, as far as becoming a confident rider.
I am not the most confident rider now but hogs have exploded out from under Biscuit's feet and we have weathered that just fine. Other horses having hissy fits are not a problem. Biscuit acting like a goober and I am fine. Biscuit will shy a little at logs on the ground occasionally (I believe he thinks they are alligators that will surely bite off his little legs!) and I am ok with that too.
I hope you gain your confidence back soon. I know how that feels - it is pretty dang frustrating.
