Monday evening, my beautiful boy (avatar) lost a battle with what I believe was dropsy. By the time he went, he was just a shadow of himself, so in a way it was a blessing because he looked so miserable. It still broke my heart, though. I felt a little silly crying like that over a fish. At least my family was understanding. It's crazy how these guys can steal your heart.
I'm very sorry for your loss. It's nice that your family was understanding because many others are not as considerate. There is no shame in mourning over the loss of a living creature in which you share a bond with.
