I’m sorry that this is happening to you and your family. Unfortunately, there is likely little you can do. She is an adult. You can’t control her behavior. All you can do is react to her behavior which, thus far, involves enduring her wrath. Don’t allow her to abuse you. If you know she abuses you via text, block her number. If she calls and harasses you again, block her number. Interact with her when she’s calm and respectful. Don’t, when she is not.
Encourage her to seek help, and hope that she will take your advice. If she is a danger to herself or others, call the authorities or local crisis team and let them handle the situation. Otherwise, you’ve done all you can.
Understandably, having so little power in this situation is disconcerting but that’s the reality. Hopefully a positive outcome will eventually emerge. You might consult a therapist (family or individual) to assist you in navigating this challenging issue. The more support and guidance you have, the better. Please take care.
