aww, Meg, I'm sorry! I know how you feel! At the farm I ride at, they had this horse Jewel. They had just gotten him a few months earlier and I was really attatched to him. One of the days I went for my lesson, they were putting me on a different horse. I asked where Jewel was and they told me he died. I think of the same thing that was wrong with Copper. Anyway, I'm really sorry. and I know it hurts so bad.
