You are getting good advice. Survivors of abuse often re-enact the abuse cycle by becoming abusive to others or behaving in such dangerous ways that abuse happens again or can be IMAGINED to have happened again.

Take major space away from this person. If she has anti-psychotic drugs, she must have a doctor somewhere and must have some clue that she needs professional help. She sounds like at the moment she is an emotional danger to everyone around her.

You need to take care of keeping you and yours safe. Pray for her and keep far far away until you KNOW she is back in therapy with a professional she is really leveling with.

Many of my friends who ARE psychologists are very wary and careful when working with survivors with unintegrated abuse issues.
