My 13 year old son has said that he keeps having bad thoughts and cannot sleep as he is worrying about his family dying. He had a really close relationship with his grandad who devastatingly passed away 18 months ago from an aggressive cancer, a few weeks after diagnosis. It seems to be a delayed grieving I know. Is there anything I can do or say to help? The problem is I say “I’m not going anywhere yet” but this sounds quite lame really as his grandad was youngish and very active and his diagnosis and death was such a massive shock and upset to us all. my son is panicking that it could happen to other family members. We all miss my dad so very much. Any advice appreciated x
