We hear about it everywhere. A doctor tells his patients, “It’s your nerves.” Sensitive and high- strung women complain of their “nerves.” We see evidence of “nerves” everywhere-in the streets, in the cars, in the theatres, in your business, and especially in your own home-right in your own family. Nervousness is not a disease ; it is a condition. A doctor may pronounce you as sound as a dollar organically and yet you may be on. the verge of a nervous collapse. What does it all mean? What is-meant by nervousness?
