I am so very sorry for your loss. I absolutely know how you feel. You did what you thought was best. You will have your moments of guilt in wondering if you did the right thing or not. I feel so much guilt for my Meela that I will never get over. I will never, ever feel like I did the right thing because of the fear and the vets I took her to. My story was different from yours, as each person's grief is also different. No matter what, it hurts...it hurts a lot. I send hugs your way in hopes of comfort to you and a prayer for Morty.
