This really. My beautiful, darling Gizmo collapsed yesterday. I rushed her to the vet immediately and they said she was having a Pulmonary Embolism. Her legs were cold and her breathing very poor, they said there was nothing more they could do. She was only 13. I've no children or family so she was literally my entire world and I'm broken. I've been awake all night crying and wondering if there was anything else that could have been done. I'm so lost without her.
