Wouldn't the sort of logical follow-on question be, "Well what would cure it?"
One thing I've noticed in my sitch is that whenever WAW appears (to me) to be like her "old self," she seems to throw this switch to become a total B*tch-on-Wheels. Like she's overcompensating for some secret knowledge she has. It really manifested itself yesterday, in fact, when she said more-or-less the same thing Mrs. Thinker said in response to a comment of mine that was more-or-less the same thing Mr. Thinker said.
She had emailed idly about the kids (who are with her this weekend) and how much fun they were having in the pool: "I just watch them. I don't what it is. I just watch. I'm tired all the time. I'm not interested in anything....." and more to that effect.
Well you don't have to be Dr. Phil, right? I mean, pretty classic signs of situational depression. So I said what you seem to have said. Response: Blah blah blah, psychobabble you've been reading, blah blah blah, and anyway this isn't something you can cure with a pill.
So I asked her, "Well what would cure it?"
An end to all this craziness.
And then I dropped A bomb -- "And what would be different about you the day after all this craziness ended? Not about us. Not about the situation. What would change in you?"
The silence since has been deafening.
No, I think @Sara's definitely on to something, and that you've been picking it up as well. I wonder if somehow that's not always the case? I mean, I wonder if The Fog is some kind of mental condition, temporary insanity, something? Someone -- maybe @Sara, in fact -- mentioned up-thread a bit that the death of a parent seems to play a role in a lot of these D-sitchs. Did in mine. Plus so many of us are in the mid-30 to 50 range, where one is conventionally assumed to be getting all comfortable and content and whatnot. Hmmmmm. Makes me think -- and that's always a dangerous thing.
