Psychological stress
In psychology, stress is a feeling of emotional strain and pressure. Some stress, called "eustress" or good stress, may be beneficial, motivating people to perform better. It is not defined by the level or type of stress, but rather how the individual perceives the stressor. Distress is the opposite of eustress. Psychological distress is an aversive state in which a person is unable to adapt to stressors and shows maladaptive behaviors, such as inappropriate social interaction (aggression, passivity, or withdrawal). Excessive amounts of distress can increase the risk of illness.
