Id, the instinctual part of the personality and contains all the basic drives and emotions that come from the aminal nature in humans.

Superego, the total opposite of the id. It encompasses cultural values, ideals and rules of conduct, and society's standard.

The id and the superego are always in conflict, to mediate between the both of them, we need a third structure called the ego. The ego ensures that the drives o the id are reasonably fulfilled without disturbing the superego; the ego is brought into play by anxiety which is triggered by any potential conflict between the id and the super ego. If the ego cannot handle the conflict, the result is neurosis.

Neurosis

A compulsive person is a neurotic (compulsive neurosis) who spends a tremendousamount of energy in keeping things clear and orderly, even when it is not necessary. This symbolises the effort to keep id impulses under control. In contrast, people who suffer from anxiety neurosis are usually easily frightened, and their transform their anxieties into ovsessive and unwarrented concern about their personal health, or into fears which have no basis.

Neurotic personalities experience too much anxiety and guilt, while the neurotic character experiences too little of it. Because neurotic characters do not suffer anxiety, they are less likely to come for treatment and feel that it is the world, and not themselves, with the problems. This may also lead to psychopathy, as they can inflict pain, suffering little, or no guilt or remorse.
