I am so sorry for you and mommy. It is a difficult part of life. You bare no responsibility here. Please be kind to yourself and know that the mare needs lots of extra attention. Horses remind me of elephants in their grieving. Elephants actually have a burial ground and they go there and hold the bones of their loved ones and mourn. I guess they are a lot more healthy then we, the human race is. Please take care. You are such a loving soul and I know this hurts. I want you to be okay. yeah, I know I am selfish. Peace.
