I've been lurking for a long time, but thought I'd come out of the woodwork for this. I'm very familiar with the DSM-V and I've spent a large part of my adult life conducting mental health assessments. It should be noted that you can't diagnose without knowing how a symptom or behavior affects the person's life, as impairment in functioning is part of the criteria, so like bluesneakers said, there's no place for internet diagnosis. That said, I haven't seen anything here or on what I've seen of SW's SM that would convince me that she meets criteria for any mental health disorder. Yes, people who are manic may spend a lot of money. That doesn't mean everyone who buys a lot of stuff they don't need has bipolar. People with borderline are impulsive, but so far I haven't seen anything that suggests she's impulsive or has unstable relationships. SW liked a neat house. That doesn't mean she has OCD. (Huge pet peeve of mine. OCD does NOT mean that you just like things neat. It's so much more than that).
Of course we're going to speculate about the mental state of both SW and CW, but it's irresponsible to try to diagnose from her SM.
