OMG! I CAN CANTER! but I need help :L?

I think you want us to address the mental part of the process, how to stop worrying about the canter, right? You have to stop imagining all the dreadful things that might happen, and picture yourself sitting a beautiful canter, calmly and brilliantly! You can't relax your muscles and thereby sit the canter following your horse's motion if you're all in a tight knot due to anxiety and fear of falling. Usually falling is not a big deal, anyway. All of us who have been riding for years and years, and who ride all sorts of horses, the good, the bad and the ugly, have hit the ground a few or many times with nothing much damaged other than our egos! And a little bit of dirt down our breeches. Be brave!
