Sorry this may be a bit long. Last July I finally had enough money to get my first horse aged 26 So started the search saw a few none really sutiable. Then viewed this lovely tbX mare who was amazing rode in the school no problems lovely paces top of my budget but thought she would be worth it. Took her in a field (the school wasn't great) saw her rode in there before i got on walk, trot all good started to canter then she fell I thought i was OK but decided not to buy incase this is a common occurance. The day after i couldn't walk went to casualty all not good with the inside of my left knee swelled to 3/4 times it's size and half my leg went black with the bruising. Now in january and my knee still hurts a bit. This didn't stop my search for a horse and found a lovely balck gelding Zak, we have only been walking and small trots due to my injury but now it's feeling a bit better decided to canter him for first time today and couldn't I just froze and carried on trotting. I don't know what to do I have never been scared of cantering before my RI says just do what i'm comfortable with for now and the canter will come, but it's frustrating I really want to canter but when the opportunity is there I can't take it. I don't know how to overcome this, any suggestions would be appreciated.
