This is one of the areas in which therapy and medical treatment differ greatly. With medical treatment, the best result is a cure in which the disease is eradicated and ensures that it does not return. In therapy, this is not possible because mental illness, negative beliefs, and maladaptive behaviors are not diseases. psychotherapy is a collaborative treatment based on the relationship between an individual and a psychologist.
Based on dialogue, it provides a supportive environment that allows you to speak openly with someone who is objective, neutral and non-judgmental. You and your psychologist will work together to identify and change patterns of thinking and behavior that prevent you from feeling better. Regarding the first question, whether therapy helps everyone, the answer is that there is nothing in this life that is true for every person. There is too much diversity in temperament, lifestyle, economy, personal motivation, personality, etc., for any universal truth about therapy to suit all people.
Contrary to what some believe, even Sigmund Freud, the first real modern psychotherapist, saw people for no more than a year and many for a shorter time than that.
