I have a friend. I think she has Munchausen syndrome. I can't give her the support she needs (basically endless streams of stuff on whatsapp).
We are in a group which is meant to be general chat and about our shared hobby.
I left that group and started a new one with the same people, but a more pointed title for the name of the group. She's started up on there now.
Right now it's also a trigger for me as I approach the anniversary of my Mum's death.
I took myself off rather than tell her, which was maybe cowardly of me.
