If you’ve asked her in a calm manner multiple times and nothing has changed; then it is out of your control. Just remind her that her actions are risking your well-being also, not just her’s. If you feel as though it has gotten to the point of life or death, you have to contact the authorities. I know doing such a thing is very difficult, but you HAVE to muster the strength. I’m sorry that you have to experience such stress. You deserve better. I hope everyone in your family turns out okay and that you and your mother live long, safe, & happy lives.
