We do the best we can. Most of the time, the outcome is not up to us and that is hard to accept.
Don't think of losing him. Picture him finally out of pain and suffering and running in the meadows in Rainbow Land! I know you are sad, but he is happy and free to enjoy his existance!
You will see him again.
This brings to mind all of a sudden about my experience with Willie. You know I've sent many off. I try my best to remain strong and to comfort them as they go off so they are not scared. For some reason, with Willie I sobbed in his fur. When I talked with Latifa, he wanted me not to be so sad because he was fine and he wanted to move on and be happy. I put my hurt aside....wasn't easy but I did it.
More hugs my friend
