Yeah it is sad, that she doesn't recognize the need for help. I did try with the police, but the reaction I got from them, was, "yes she's delusional, but she's not an immediate danger to herself or others."
I'd argue that at this point she is a danger to herself as she obviously can't take care of herself.
About the only other thing I could have tried, and I was thinking about it, before things blew up, was going to a Justice of the Peace, and asking them to issue a warrant for a mental health exam. That would give the police 7 days to pick her up and take her to a hospital for evaluation. But now that I have absolutely no idea where she is, it seems kind of pointless.
