So very, very sorry for your loss. It is so very hard to let go. You did what was best and what had to be done. It seems to me though that having this happen in the middle of the night is much worse than daytime. You seem to be more vulnerable. I had to put my dear ferret Miko to sleep at 3:30 am on January 20, 2006. It was much worse for me than any of the others. In time your heart will heal and you will feel better. Hugs for you.
