Obviously COVID being everywhere isn’t helping, but we’ve also had two close family bereavements in the last year and DS who is nearly 9 is just spiralling out of control with his anxiety about illness and death. We watched a film over Christmas that had a character who had cancer (they recovered!!) and the only symptom they mentioned was feeling tired. Since then every time he feels tired he becomes hysterical and is frightened to go to sleep because he has also heard that people ‘pass away peacefully in their sleep’. There was a trailer for a film on Netflix about Everest where someone was suffering from altitude sickness. I’ve just had an hour of absolute hysteria about ‘catching altitude sickness’ and he’s only just fallen asleep next to me 
this is after a nice day full of exercise, warm bath, stopped screen time at a reasonable hour, had an audio book, read to himself calmly etc etc. Then as soon as it became time to actually go to sleep he just lost it completely.
This is becoming such a vicious circle and I don’t know what to do about it. Do I take him to the drs?
We are also moving house as well which has been hugely delayed so he’s clearly picking up on all the anxiety about that. He’s also desperate to see grandparents and heartbroken he can’t see them yet. It’s so upsetting seeing him so sad and anxious.
Any help or solidarity much appreciated!
