Self-punishment Mechanism
He feels that he deserves punishment and therefore is constantly anticipating that punishment. As a result he lives in a constant apprehension that something is going to happen. In order to find peace under these circumstances he must increse the intensity of his activity. He feels that hard work will give him some release from his sense of guilt. A physician told me that in his practice a number of cases of nervous breakdown were traceable to a sense of guilt for which the patient had unconsciously attempted to compensate by hectic overwork. The patient attributed his breakdown not to the sense of guilt, but to his overworked condition. "But," said the physician, "these men need not have broken down from overwork if first the sense of guilt had been fully released." Peace of mind under such circumstances is available by yielding the guilt as well as the tension it produces to the healing therapy of Christ."
