Obsessive-compulsive disorder is a battle between compulsion and counter-compulsion, an internal battle of thinking activities, a battle in which there will be no winners, an internal battle in which thinking power is used up and a great deal of the individual’s energy is expended, but a battle in which there will be no result and the individual will be in agony and unable to get out of it. Why does this battle happen? What is the compulsion? And what is the counter-compulsion? What is the relationship between them? This series of questions needs to be answered. Compulsion is the exertion of pressure to make oneself obey, to compel, to force others or oneself to obey based on one’s own will. Compulsion here refers to self-oppressive ideas and compulsive behaviors. For example, repeated checking, repeated washing of hands, laundry, and sanitizing furniture. The individual perceives these compulsive ideas and behaviors as unnecessary or abnormal and against his or her will, but these are the individual’s own thoughts or impulses. If they are the individual’s own and against the individual’s own will, how come these ideas and behaviors pop up again? One possibility is that the individual’s own control is weakened; another possibility is that the individual is overly concerned about a certain area and is reacting irrationally and emotionally. If these reactions are directed at the individual’s own self, the individual may develop a tendency to be suspicious, and instead of feeling wrong, the individual may dwell on it. If the individual perceives these obsessive-compulsive symptoms as unnecessary or abnormal and against his or her will, and resists them vigorously and strives to control them, counter-obsessions can develop. The compulsion seems to be irrational and the anti-compulsion seems to be rational. The intense conflict between compulsion and counter-compulsion will not result in anything but anxiety and distress for the individual, and gradually the individual will experience impaired social functioning. This conflict consumes a lot of energy and becomes a kind of hard mental labor for the individual, which further depletes the already insufficient energy and gradually affects the normal life. It is even more difficult to restore the individual’s normal energy. If recovery is to be achieved, the first step is to block the conflict between compulsion and anti-compulsion, and then gradually restore the individual’s energy and control. Most of the obsessive-compulsive disorder has an obsessive personality. Personality is a habitual pattern of behavior that is highly stable and inertial, which also makes the treatment of OCD difficult. It may be more effective if treatment goals are more easily achieved with the help of medication and then combined with psychotherapy.
