The feeling of needing to be forgiven.

Guilt is an affective state in which one experiences conflict at having done something that one believes one should not have done (or conversely, having not done something one believes one should have done).

From Wikipedia;

Guilt is a cognitive or an emotional experience that occurs when a person believes or realizes—accurately or not—that he or she has compromised his or her own standards of conduct or has violated a universal moral standard and bears significant responsibility for that violation. Guilt is closely related to the concept of remorse.

Guilt is an important factor in perpetuating obsessive–compulsive disorder symptoms. Guilt and its associated causes, merits, and demerits are common themes in psychology and psychiatry.

Sigmund Freud described this as the result of a struggle between the ego and the superego – parental imprinting.
