I had no major injuries but had a horse that had my number. He would go out and work all day with my part boarder but I was more tense and that led to him being more tense and misbehaving. I love this horse on the ground and still have him but he is now retired and I have a new horse.
Horse number 2 is the horse I should have had a long time ago. He is big but he is so well behaved. I am certain I could have a full blown panic attack on him and it would have no impact.
I got him in the winter, so indoor riding ring and everything was great. We got along well and I was starting to let go of my anxiety and doing things with him I hadn’t done in years. Fast forward a few months to spring and riding outdoors. I went to the mounting block in the indoor arena with plans of walking around and then heading outside. Suddenly I couldn’t even get on. I was on the mounting block in tears and unable to put my foot in the stirrup. Thankfully my coach who is also my brother was able to understand the pressures I was putting on myself and was able to talk me off my ledge. I finally got on. He led me around the indoor and then led me outside. He made me realize I had nothing to prove to anyone. That i am doing this for myself and my enjoyment and that if this is all I can do on that given day then that is fine.
The other thing that he said is that almost every adult amateur that he has coached has gone through this at some point in time. This was very eye opening as we think it is just us dealing with these issues.
Good luck and take it day by day and do what you are comfortable with. Somedays it might be a lot and then another day nothing.
