My dad passed away of lung cancer in 2016 and I still can't get over it. I still think of him every day and wish o could talk to him all the time. I still think it's so u fair that he was taken at such a young age and I'm still angry and upset about it. I can't speak to my siblings because they had a different relationship with him than I did. He was my hero and my best friend right up until he died and my two sisters didn't get along with him until he was diagnosed. I just want to know how to deal with it and how to stop being so upset all the time.
