Soooo...Now I'm on this horse and it just plumb freaks me out because, well...I'm up in the air and I'm pretty sure God mad me a ground dweller!!!!
What I did to give myself confidence in the saddle was to practice jumping off the side of the steps that lead to an old barn on my property...LOL....The top step is about 4' off the ground and to most people they wouldn't think twice about hopping of of it. It took me convincing myself that I wouldn't die while I was falling... I don't mind crashing and rolling on the ground...It's the sensation of the fall.. Egads that just does a number on my stomach, Like I'm out of control... almost like a wind gush up from my toes and gets caught in my chest...Truely and eerie feeling.
Once I jumped a few times, I began to be able to control my guts and learned to supress that feeling. Not that I don't still feel it, but I know it will be OK. More like I learned to tolerate it...Like the annual trip to the Gyno...You just tolerate it.....lol.....
Sounds like you have a great horse. Spend some time with it, learn to trust it from the ground. Then tackle your fear...disect it and figure out what part really pushes your buttons...Then figure out a way to overcome it. In my case I found that by breaking the fear into bite size pieces I was able to deal with it.
GOOD LUCK!!!!!! Hope I helped some!!!
