Hugs to you. I completely understand how you are feeling. We had to make the same decision two months ago. I still feel guilty, but I know I did the right thing in the end for Rusty. If we would have opted to bring him home, it would not have been for him, but for us and that would not have been fair to Rusty. You did the best thing that you could for your pup. He is now running pain free.
