I'm kind of done with this conversation.

One concluding footnote. It seems to offend you a lot that I called that one sentence 'bad writing'. I want to point out that 'bad writing' has been the more generous explanation of the strangeness of that particular sentence. A slip of the pen is no big deal, it happens all the time.
It would be quite a bigger accusation if I insisted, like you, on taking that phrasing completely at face value, and then called the author a nutter for endorsing a model like that.

(Of course, a still more generous interpretation would be that the word 'anxiety' is being used here in a specialised way with a very narrow definition, and that the apparent absurdity here is just a matter of lacking that context. Which you're now hinting at by calling the rest 'fear' -- supposing that that's a separate class of feelings -- but still haven't explicitly confirmed or denied.)
