Its such a shame that you feel this way, but I'm sure it'll turn out all right! Visit horses and hopefully you will get back the pure enjoyment you can get from horses. It may be difficult to actually get on the horse but just think about what you will be thinking as you are trotting or cantering the horse, I feel like a weight has just been lifted from my shoulders. Its difficult for others to motivate you, you have to do the real motivating yourself.
