Jen, give yourself a big pat on the back. Fear comes to a lot of us. After
being thrown and injuring my back I couldn't ride for a year - fear was well
entrenched. Found a positively quiet horse and walked and trotted only for two
years with a good friend. I have to second Chris' recommendation on singing and
breathing. Had my husband drop me and horse off 9 miles from home, all alone.
Old fear resurfaced, especially because the mare was picking up on my
nervousness. Then I remembered singing (and thank God ONLY my horse could
hear me!) But my horse visibly relaxed, and I became more confident. Like Chris
said, if you're holding your breath in fear your whole body is tense and the
horse feels it. Just keep at it, a little ride at a time, as you are comfortable
with. Good luck and keep us posted on your progress.
