You could try casting out demons from her. In the name of Jesus Christ. If she is out of the room and earshot, they can still probably hear your command.
I told my husband this morning that I think she needs an exorcist more than a therapist. He laughed.
When I say scary, she can be all sweet and normal but say one thing she doesn’t agree with and you can see the crazy in her eyes. Her entire body language changes right before your eyes. Her head drops down and when she looks back up, the expression on her face and in her eyes makes you think you are getting ready to be punched. I have never experienced anything like it. I don’t know much about severe mental illnesses, but I have read that they can act this way. She claims to have terrible night terrors and PTSD. I don’t know of anything in her life that would have caused all of that. I don’t recall ever spanking her. Maybe I should have. My dad got physical when he was stressed so I got knocked around some. He never truly hurt us, but I said I’d never do that to mine, and I didn’t.
I’m getting ready to amend my will. No way, at this time, she is sane enough to inherit this farm if something happens to me. I don’t think I’ll tell her though. :-)
