The best suggestion is not to explain yourself or defend the crazy stuff she says. She is still full on in blame mode and she while she can admit she is not well, she still is not taking an ounce of accountability.
Your best bet? To let her ramble and not say a word. I can't see anything else that you can do.
If she is still in a place of blame shifting, her seeing D's may not be a good idea. I know there was nothing more painful to me than my mother blaming me for adult problems.
You will get a sense of whether or not she is ready to take accountability. Or at least if she is on the path to it. But until she is, I wouldn't be facilitating a meeting and "helping" her like she asks.
You continue to absolutely amaze me. I would have had her blocked from my phone by now and only entertained email to an account just for her to email and to check it when I see fit. You are a better person than I.
