My wife has found ChatGPT extremely useful when dealing with her mother - who has bipolar and is obsessed with other people's health. I've got a terminal cancer diagnosis and handling my mother-in-law has been extremely difficult - nearly to the point of no longer having any communication with her. ChatGPT has a single conversation with all the back story and has put some useful points across when discussing how difficult her behaviour has been (she watched a operation that failed for me for entertainment, for instance).

I have found similar when giving backstory and needing help to start structuring difficult conversations where I want to say the right thing but also need to be sensitive.
