Obsessive-compulsive neuroses often result from a recurring repression of feeling or behaviour that is considered socially unacceptable, physically harmful, or morally wrong. When the obsession arises from repression of feelings, the type will be specified by the emotion repressed and frequently may also be related generally to the sexual instinct or the drive for self-assertion. Repressed emotions gradually react from the unconscious level, manifesting themselves by compulsive actions, some of which are not immediately evident as related to the repressed emotion. Obsessive-compulsive neuroses require treatment by psychotherapy; however, proper treatment is often not provided and individuals may spend an unhappy life-time with these conditions and cause additional unhappiness to those around them.
