I feel your pain most entierly! My horse did the same thing and its the longest thing in your life that you have to go through! I just always remember my grandpa saying that it does not matter how long it takes to heal or how he might change its that he is alive and breathing! My horse is almost a different horse after his accident, but all I care about is that he is still here! The day that you get to ride him again will be the happiest day of your life! I think I even shed a few tears! You have done amazing with his leg, and it will all pay off very soon!
