Some people contemplate their lives and realize they are dissatisfied. They realize that missed opportunities have passed and that they have not accomplished what they wished. According to the theory of psychoanalyst Erik Erikson, these individuals experience __________.

Psychoanalyst Erik Erikson maintened that from childhood to adulthood the personality of individuals is developed according to 8 stages of psychosocial development, where at each stage there is a psychosocial crisis, which occur due to the conflict of psychological needs with social needs, and which result in positive or negative effects that will form the personality.

The last stage of Erik Erikson's theory refers to the conflict of ego integrity versus despair, usually affecting 65-year-olds and lasts to death.

The psychoanalyst believes that integrity is the positive characteristic that occurs when the individual is proud of his lifelong achievements and sees his journey as successful.

The negative characteristic of this phase is despair, whose perceptions of the individual are to blame for the past, desired and unreached achievements, and dissatisfaction with life, which can result in illnesses such as depression.
