hii,so ive been starting canter and it really isnt going good,im the leader of the line which simply makes me more scared because my coach just yells saying im not paying attention to the line,i only canter in a line of 4-5 so when the class ends i canter for some minutes and i have to change my horse,the horse i use to canter with is literally a beast,even my coach once struggled controlling it,so i canter with him and i cant keep myself on the saddle!and my coach just yells which makes me more anxious and makes me do even worst.i keep falling on his neck no matter what i do!i just get bounced up and to his neck and some people watch me do it and its so embarrassing,i dont know how to fix my canter and i really need help!itd be wonderful if someone could tell me how to control the horse and keep myself from bouncing.
