I know you are heartbroken, but when we had Tomas PTS, from renal failure and old age, we drew comfort from the fact he was no longer suffering. He went almost exactly the same way as Ash. Lost a bunch of weight, stopped eating, just literally gave up. I drew comfort from the idea that he felt much better and was playing again. I hope you can do the same. Please know that Ash thanks you for your loving decision, as hard as it was for you to make. You are still in my thoughts and prayers!
