Relative "Susan" has a schizoaffective diagnosis and has been this way for decades, some of my earliest memories of her were during episodes where she'd become violative and dangerous, sometimes towards DM and on many occasions cause a scene in public places. I remember a lot of police intervention and many, many hospital sections throughout the years.
She regularly comes off her medication and declines, resulting in being sectioned and another hospital.
A clear pattern has emerged where she'll stop taking her medication whenever she feels she's not getting enough attention, she is somebody who wants people to spend a massive amount of time with her regardless of DC, relationships, jobs etc. When members of the family are busy and can't spend a lot of time with her or need to focus on something themselves, she'll stop taking her medication yet again.
Due to how she presents when unmedicated I'm not prepared to allow her to spend time at my house or in the company of my DC, the things she comes out with and how she presents makes me anxious and I don't want my DC exposed to erratic and unpredictable thoughts and behaviours.
AIBU? Shes sent me a very emotive message saying how she feels rejected and cast aside.
