SIL has a long history of health anxiety and Covid has pushed it through the roof. It's dominating her life.
The problem is that she's getting very anxious about what other family members are doing and asking them to modify their behaviour. We are modifying some things, and lying / not telling her about others.
She's now wanting to control my mother (her MIL)'s contact with her grandchildren.
She has risk assessed her own mother's contact with grandchildren and is happy for her mother to see her grandchildren, but wants to reduce my mother's contact with her grandchildren.
My mother is unhappy but SIL has been so distressed lately that she doesn't want to risk exacerbating things.
Mostly it seems to be about control - she's happy to meet her friends in Cafe A (because she's risk assessed it) but doesn't want other people meeting their friends in other Cafe B or C which she hasn't risk assessed.
Her own social life isn't reduced (because she risk-assesses) but she wants other people to reduce their social life.
An example of something we've kept quiet is that DH and I attended a funeral. It was in a large church, there was social distancing, everyone did a LFT first, everyone had to sign in for tracing, everyone was masked. But SIL doesn't think anyone should be attending funerals. So we have pretended we didn't go.
While we were at the funeral she was shopping in a shopping mall, which she had risk assessed as safe. It makes no sense that a socially distanced funeral is most risky than spending a couple of hours in a shopping mall, but SIL isn't making sense.
My mother is upset, but feels she has to comply in case my SIL's mental health worsens.
Does anyone have any experience of this sort of situation?
