"Check Heidegger. I would agree with him that we do a lot better treating anxiety (some forms, at least) as a kind of beckoning of the self to a self rather than as a symptom of illness. This is why in writing novels I often find that it works to turn things upside-down and to set forth a character‹say, a woman with severe free-floating anxiety‹as more interesting, more hopeful, possessing greater possibilities than, say, another perfectly adjusted symptom-free woman. To say this is to say a good deal more than that illness is more interesting than health."
