I'm just interested what was the breaking point for anyone who was in this position. I think I am at one right now with my mum. She has undiagnosed bipolar (we are 98% certain as are her Drs but she refuses help from a psychiatrist). Makes it a bit more complicated as I have a much younger sister (13 year old) who still lives with her and I am very close to.
However, I can't really carry on like this. I've minimised contact as much as possible but it is all just making my mental health go to shreds and I am a quite strong person mental health wise.
