Congratulations and a job well done! Be very proud of yourself for taking that step forward and empowering yourself to get the courage to take this giant leap ahead!
I have fear issues as well, where stadium jumping is involved due to an accident I had a few years ago with a previous Coach of mine, and it's taken alot of time, work and empowerment to get myself to the heights I am now doing.
I went from breaking a sweat and crying when my now current coach asked me to do an X rail, to getting comfortable with that and then moving up slowly and surely...now I am at 2'11"-3'0" with confidence and I am so proud of myself for what accomplishments I've achieved from that X Rail, to the 3'0" fences.
Be proud of yourself for every little accomplishment you make, because before you know it, when you look back to see what you've done, you'll discover that those little accomplishments, accumulated into a huge one!
I love your Appaloosa, what a doll!
