Me and my dad have always been best friends. I'm 27 and he's 72. 13 weeks ago today, we were getting drunk together and dancing and then two days later, he had a fit while he was watching TV which led to stage 4 lung cancer diagnosis with brain mets. First two months he was ok and then 31St Oct he got lung clots and pneumonia and everything went down hill. He started to get confused just around a week ago and his personality began to change. (not sure whether the pain meds or brain tumour caused this) and he kept muddling his words up. At first he was confused but still there. Then he was seeing things in the corner of the room that weren't there. Then he lost interested in football completely. He's been getting worse each day since. Now he stares at me vacantly when I talk to him. He started punching me the other day and threatening to kill me but he's too weak to move. This is not my dad. He has always been so loving and kind. The doctors came to assess him and they say he has days to live. It's so difficult.
