hey ok so i need some help...

I have been riding for about 9 years. I’m 15 now. My family comes from a long line of horse people and ride western. I took lessons for 2 years western then my family moved(were military). I did not ride for a while only when i went to see family. Then i get my first horse she was for me and my brother(Dixie). She was a wonderful little girl and beautiful. But i quickly out grew her also i wanted to make the change from western to English. So again i had no horse to ride. About five months after that i meet a girl out at my barn where we keep Dixie. She is 25 and has rode hunter her whole life and was willing to give me lessons on her horse so i took lessons from her for about 3 months. Then i found out my uncle was selling one of his horses a AQH he was a wonderful horse out on the ranch and i always rode him. So we buy him thinking i would not be hard to train him as a hunter well me and my trainer. i was and am the only person in my family to ever ride English. So we get him and he was horrible kicked bit and would not let us saddle him it was bad. so finally my trainer got him saddled him and go on... it was the ride from hell. I still think to this day it was because he was used to being on a ranch not in a stale on grass not grain. So we sent him of to a trainer for 3 months and got him back he was a different horse i mean still a pain in the ass under a English saddle but wonderful i western. So we work him hard every day and he slowly improved. I was happy i could control him under the trot and over cross rails. So my trainer entered us into a flat- walk trot class at a local schooling show. It was amazing and he was wonderful but we did not place because i was on the wrong lead. So i went home very happy! After the show my family went on vacation for 3 weeks and my trainer could not get out to ride him but once a week. when we came back school was about to start and i had little time to go see him. I was out on the trail with my trainer and a friend and blaze(my horse)got down and tried to roll. we took him back to the barn and called a vet he had a mild cases of colic but i could not ride for 2 months. After the 2 months were up i got back on and no joke was on for less than 2 seconds. So now only my trainer can ride him . Then i start ride at a big barn where i pick up my game. So i had been riding there for 2 weeks when my new trainer tells me she is leaving because she is having problems with the owner of the barn. So some one new takes over my lessons. This person did not know me and put on a more advanced horse who is huge almost 18.2 hands( well that’s big for me) and she pushes me in to a canter for my first time under English saddle Wilson takes off and its going good till he spokes and throws me. I broke my arm and caller bone. So now i don’t trust any one at the barn and have a mad horse on my hands. My family keeps telling me to switch back to western and keep blaze but after all my work riding hunter i really want to keep riding. I know your at risk when you ride horses but i am really scared to get back on. I would love to keep riding hunter and show but i am 15 and now cant canter or jump over any thing but a cross rail. I don’t know but i feel like giving up. I just want to know if any on is in the same place that i am. And do you think i would be able to make it in the show world? sorry it was so long.
