Well, there's the suggestion that in the aftermath of Sept. 11 producers felt that audiences wouldn't warm to the story of a depressed college student - her experiences seemed insignificant in comparison. Wurtzel also got a lot of bad press for describing the attacks as "beautiful" and saying she felt no emotional response to them (this from a native New Yorker.)
Although, "Girl, Interrupted" got made, so hey-ho.
My personal theory is that tptb decided their heroine wasn't likeable enough.
Yes, I understand. For me it can be bit like a fog around me. I'm so focused on myself and what I'm going through that I can't see outside of myself or think of the people around me. I've treated my frienRAB and family horribly at times, but I see depression as a reason for that, not an excuse.
I'm actually glad that Wurtzel is so honest even if at times that means she's unlikeable.
To the poster who asked if it was worth reading - I'd say yes, though at times Wurtzel can be frustrating.
