Oh Tracy I am just so sorry. That is terrible. It is so hard to not feel guilty, but as you said you know it is time. They are in pain and miserable. That isn't any kind of life either. Sigh... I still beat myself up about the last 3 I had to put down. Did I wait too long did I do it too early? It is never easy. But you gave them a wonderful life and they know it and they love you.
Big HUGS to you and your family.
