What about depression, dittany? In the article, she did approach doctors and the article implies that their response - that it wasn't classic depression - felt like a brush-off.
I don't deny there may be reasons for her situation that she (as is her right) doesn't want to share. But I do believe it could also be just as she says, that she can't pinpoint a reason other than her reactions to alcohol.
I think that to say there must be a negative reason for her situation, is to buy into the idea that women are natural paragons of virtue, and any who slip from that ideal are therefore so much the worse than men.
(I am just feeling my way through this reaction of mine, so sorry if it's poorly expressed.)
