=The Real Sufferers.= These so-called normal people are merely on the fringe of nervousness, on the border line between normality and disease. Beyond them there exists a great company of those whose lives have been literally wrecked by "nerves." Their work interrupted or given up for good, their minds harassed by doubts and fears, their bodies incapacitated, they crowd the sanatoria and the health resorts in a vain search for health. From New England to Florida they seek, and on to Colorado and California, and perhaps to Hawaii and the Orient, thinking by rest and change to pull themselves together and become whole again. There are thousands of these people--lawyers, preachers, teachers, mothers, social workers, business and professional folk of all sorts, the kind of persons the world needs most--laid off for months or years of treatment, on account of some kind of nervous disorder. =Various Types of Nervousness.= The psychoneuroses are of many forms.[3] To some people "nerves" means nervous prostration, breakdown, fatigue, weakness, insomnia, the blues, upset stomach, or unsteady heart,--all signs of so-called neurasthenia or nerve-weakness. To others the word "nerves" calls up memories of strange, emotional storms that seem to rise out of nowhere, to sweep the sky clear of everything else, and to pass as they came, leaving the victim and the family equally mystified as to their meaning. These strange alterations of personality are but one manifestation of hysteria, that myriad-faced disorder which is able to mimic so successfully the symptoms of almost every known disease, from tumors and fevers to paralysis and blindness. [Footnote 3: The technical term for nervousness is _psycho-neurosis_--disease of the psyche. There are certain "real neuroses" such as paralysis and spinal-cord disease, which involve an organic impairment of nerve-tissue. However, as this book deals only with psychic disturbance, we shall, throughout, use the term _neuroses_ and _psycho-neuroses_ indiscriminately, to denote nervous or functional disorders.] To still other people nervous trouble means fear,--just terrible fear without object or meaning or reason (anxiety neuroses); or a definite fear of some harmless object (phobia); or a strange, persistent, recurrent idea, quite foreign to the personality and beyond the reach of reason (obsession); or an insistent desire to perform some absurd act (compulsion); or perhaps, a deadly and pall-like depression (the blues). As a matter of fact, the neuroses include all these varieties, and various shades and combinations of each. There are, however, certain mental characteristics which recur with surprising regularity in most of the various phases--dissatisfaction, lack of confidence, a sense of being alone and shut in to oneself, doubt, anxiety, fear, worry, self-depreciation, lack of interest in outside affairs, pessimism, fixed belief in one's powerlessness, along whatever line it may be.
