From this demonstration, Freud realized the power that the mind had on the body, and he came back from Paris, determined to make a name for himself in this new field of study. When he came back from Paris, Freud immediately married his sister's friend Martha Bernays. At first, the other doctors laughed at him and nobody bought his books. He was therefore very poor and in addition, he had a growing family to support. His only friend, Wilhelm Fliess, lived far away in Berlin. Freud called that time his "period of splendid isolation". Like many others at that time, the Freud family had to suffer many hardships, firstly during World War I, and then during the economic depression, when Austrian money became worthless. Often, Freud had to analyze people wearing his overcoat because he could not afford to heat the consulting room. Gradually, more and more people came to see Freud and with each patient he tried to learn something new about his work. He also tried to analyze himself !!! During the period from 1895 to 1900, Freud developed many of the concepts that were later incorporated into the psychoanalytic practice and doctrine (free association.) and he abandoned the use of hypnosis. After many years of existence, the increasing recognition of the psychoanalytic movement made possible the creation of a worldwide organization called "The International psychoanalytic Association" (1910). (Britannica).
As said previously, Freud was a medical doctor who was interested in charting how the human mind affected the body, particularly in forms of mental illnesses, such as neurosis (1) and hysteria (2) and in finding ways to cure those mental illnesses. For his purpose, Freud created a new form of therapy which was called "psychoanalysis". It is based on the observation of many of the factors, which determine the emotion, and behavior of an individual. These factors are unconscious and they are the basis of a certain unhappiness, sometimes in the form of recognizable symptoms and at other times as troubling personality traits, difficulties in work or in love relationships, or disturbances in mood and self-esteem.
