Have Mental Health Questions? Ask a Psychiatrist Online
Hello, I am Rafael. Thanks for asking your question - I'm here to support you. (Information posted here is not private or confidential but public).
I ma very sorry to know about this real nightmare.
Unhappily there is not much you could do to change her serious situation and further worsening, buy you need to make sure you make everything possible to protect from her preventing any form or abuse, violence or harm to your integrity.
I do not see an alternative here but to get a restraining order t=and to be very careful from now on, since it would not fix things, just allow you to protect yourselves and when a new episode arises you would have the legal means to request support to be enforced to stop her, and for her to receive some support. This is not easy at all, but that's what you can do.
