conv: My father had a large tumor removed from his kidney. They thought the surgery successful and he was recovering. On the third day he passed away suddenly_comma_ with no known cause of death. My family is still hasn't recovered from the untimely passing of my father two years ago. I am so sorry to hear that. It can't be easy for you and your family. My siblings and I are managing_comma_ and have found some peace. My mother is a different story. It was just so sudden and unexpected. No doubt it will take time to process. I wish your family the best. Stay strong my friend.
