Welcome, Positronicus!

Based on what you say, it sounds as if this woman's problems are worsening and she needs more medical attention than she's getting.

I do agree with blufox9654 (welcome, blufox9654!) that any medicine she's taking should be carefully investigated. It might be as simple as adjusting the dosage of one of them.

But you say this has been going on since the 1980s. The chances are that she'll need a thorough workup--a physical exam as well as a psychiatric evaluation by someone who is known to be conscientious and careful.

Some psychiatric "diagnoses" are made in a shamefully unprofessional way, though. There are psychiatrists who will diagnose someone as paranoid schizophrenic after an interview of only 10 minutes.

So I hope that she will be willing to get COMPETENT help, and soon. Maybe you or someone you know is able to encourage her to do that. I hope so.

Children are mentioned but not their ages or what happened to them after they were removed from this woman's care. Their situation would need to be carefully considered as well.
