DM has always suffered with health anxiety (the BSE crisis was particularly memorable!) and this has become worse since the death of her DB and the pandemic. My DB is also a raving conspiracy theorist and has unfortunately filled her head with crap about the Covid vaccines.
I'm doing my best to get her to access some help through the GP and trying to keep things light and positive when we speak, I've also told DB to stop filling her head with nonsense, although that's definitely a case of shutting the stable door after the horse has bolted, she's worried sick about it all.
DM wanted me to promise I wouldn't have the vaccine until the autumn (when DB reckons the effects of the dreaded vaccines would become apparent) which I brushed off with 'we'll see' type comments as my age group wasn't being invited yet at that point. I've now had my jabs but know if I tell DM she will make herself ill worrying I'm going to die so I've said nothing. Not sure what I'll do if she asks directly as I dislike lying but honestly don't feel I can tell her as I know it will send her further into the anxious spiral she's already in.
So I guess I'm just looking for some reassurance that not telling her is the right thing to do for now. She is (believe it or not) otherwise a rational, intelligent woman and it doesn't sit comfortably with me to lie to her but I don't want to make her MH any worse, she's really not in a good place.
