Anxiety is not only the most common mental problem in the United States, it verges on a national obsession. Last year, New York Magazine declared it the signature diagnosis of our time with Xanax as its pharmacological mascot, taking over from depression and Prozac in the 1990s. The New York Times devotes an entire ongoing series to probing the anxious mind. And the online forum the Edge asks as its key question for 2013: "what should we be worried about?" All this worrying represents our own apocalyptic myopia. Before we know it, we're not just worrying about love, death, sickness, children, money—we're worrying about the worrying itself.
