Here's a thought I had.
We need to get her out of that situation for awhile, to somewhere where she can clear her head and get her mind around things. Someone in a nice, relatively stress-free environment could offer to put her up for awhile. We could put together some money to get her a ticket there, as well as getting her to and from the airport.
I'd offer to put her up if I wasn't in Australia and it didn't cost a fortune to fly from the US to here. It is, however, an example of a perfect place. It's a good 3 hours from the nearest major city, it's not quite rural but not exactly urban, and, as Dr Seuss would say, "it's not very big but quite big enough, for buyers and sellers to sell and buy stuff".
My father was just the same as this in his youth. He was depressed and suicidal. The doctor gave him anti-depressants, and that night he got drunk and took the lot... woke up 4 days later. The doctor then sent him to the country for awhile to clear his mind. He fell in love with the place the moment he got there. A week later he went back to the city, transferred out to the country and never looked back.
So I say we start a collection for SpaceCase to get her to a happy, quiet place. Who's with me?
(BlueSummers: I know you say intervention won't work, but I want to try this. The spirit of Murphy's law implies that if there are two outcomes and one is undesirable, the undesirable outcome is more likely to happen. I say we don't take the chance. We need to come together to the aid of a friend in need.)
