The best thing is to get her back into some kind of treatment. That's the only thing I can think of that will help. Psych treatment and meds. I know I did this once and I wound up losing everything for a time. It took me a couple of years of homelessness and finally therapy and the right anti - depressant and I quit doing things like that. Hopefully, that doesn't have to happen to your mother.

P.S. I like the quote at the end of your post.
