I lost my dog once. I came home and she was having trouble breathing so we tried to see what was up, but we ended up taking her to the vet. There wasn't anything that could be done, so we had to put her down. It doesn't hit you until after you leave that you just said goodbye for the very last time. It wasn't like any other goodbye. When I say goodbye, I know I'm gonna see them again. But that time was totally different. Definitely the worst feeling I've ever felt.
