Since making the hardest decision of my life, to euthanize my beloved cat Morty, I've been consumed with overwhelming guilt. I've never cried so much in my 61 years and it's been almost non stop since his passing. I don't know how to deal with the loss and keep feeling that there was much more I should have done. How can I come to terms with this? Morty trusted me and his life was in my hands and he had no way of knowing that he was about to be put to sleep and it's just agonizingly painful not knowing if I did the right thing. I am truly heartbroken.
