My sister has to have her way 100%. So if I disagree with her about something, or there is just a hint of disagreement, she will triangulate by going to other people to tell them how horrible I am. She has done this my entire life. Triangulation I mean, and not accepting that i can have a different view on something or make a decision she doesn't agree with.

I try to stay as much away from her as humanly possible because i am afraid she will try to get me hospitalized. And yes she has called the police and had them do wellness checks before. That is almost certain to tip me into instability because i find it very threatening for police to show up at my door.

She just has to have her own way and any disagreement with her is a sign in her mind of mental illness. Now she is roping my son into her drama to ruin my life.
