If you cannot afford a trainer, why not look one up and get some videos and such? I like Clinton Anderson's bending practices they are very helpful in many many ways. Im huge on bending, I think its a godsend. And I feel bending is something you really need right now. It will relax your horse, get him mind focused on your, teach him to give to the bit and be softer in the mouth, and many other helpful things. Its amazing how much simple bending exercises helps you and your horse.
