Nervousness is a _symptom_ which should always have _something done for it_, especially in children. In fact, it has passed into an axiom both with intelligent teachers and with physicians who have much to do with the little ones, that crossness, fretfulness, laziness, lack of initiative, and readiness to weep, in children, are almost invariably the signs of physical disease. And this doctrine will apply to a considerable percentage of children of larger growth. Unfortunately, one of the first and most decided tendencies on the part of the badly fed or poisoned nervous system, is to exaggerate the difficulties of the situation, and to minimize its good features. The individual "has lost his nerve," is afraid to undertake things, shrinks from responsibility, exaggerates the difficulties that may be in the way; hence the floods of tears, or outbursts of temper, with which nervous children will greet the suggestion of any task or duty, however trifling. If the nervous individual has reached that stage of maturity when she realizes that she is not merely "naughty," but sick, then this same process applies itself to her disease. She is sure that she is going to die, that another attack like that will end in paralysis; as a patient of mine once expressed it to me, "My heart jumps up in my mouth, I bite a couple of pieces off it, and it falls back again." In short, she so obviously and grossly exaggerates every symptom and phase of her disease, that the impression irresistibly arises that the disease itself is a fabrication. This view of her condition by her family or her physician is the tragedy of the neurasthenic. Broadly speaking, _no_ disease, even of the nervous system, is ever purely imaginary. Some part of the patient's nervous system is poisoned, or he would not imagine himself to be sick. We can all of us find trouble enough in some part of our complex bodily machinery, if we go around hunting for it; but this is precisely what the healthy man, or woman, _never_ does. They have other things to occupy them, and are far more liable to run into danger by pushing ahead at full steam, and neglecting small creakings and jarrings until something important in the gear jams, or goes snap, and brings them to a halt, than they are to be wasting time and energy worrying over things that may never happen.
