Once upon a time, psychiatry was reserved for only the most distressed members of society. This was always a small minority: people who were often removed to asylums, usually against their will, and subjected to esoteric treatments. Today, the few have become the many. Not because psychiatric wards have increased in number, but because psychiatric treatments and beliefs about mental distress have now crashed through the walls of the hospital and surged into every corner of contemporary life, affecting how we understand and manage our emotional lives.
