She is being cared for by her sister and is being supported by daily visits from the local mental health crisis team. She has a diagnosis of paranoid schizoaffective and is on a lot of medication.
She understands that nobody else can hear most of the voices she hears. But she nevertheless believes that the nasty and spiteful and sometimes profane things she hears from "Carrie's voice" come genuinely from me - and as a result, she feels violated and abused by what she believes I'm telling her.
I'm determined not to be upset or offended by the anger she's directing towards me (though much of what she is wrongly accusing me of would be considered extremely offensive) and I am her oldest, longest-term friend and I care about her so much, would take any bullet for her &etc.
But I am increasingly reaching the conclusion that my presence in her life is making her illness worse and worse. Or at least, that I can no longer help.
AIBU to withdraw from the friendship for the time being?
