Reception
A review in the American Journal of Psychiatry commended Hicks's phrasing of acceptable ways to speak about mental illness. A review in The National Medical Journal of India likewise applauded the book's accessibility to non-experts, though it criticized Hicks's choice of symptoms and suggested "It would be difficult for an Indian to relate to the book" due to the examples he uses. The book also received attention from Health, Library Journal, The Baltimore Sun, and The Washington Post.
