Obsessive-compulsive disorder (OCD) is a chronic, intractable psychological disorder. It is highly distressing and has a long treatment period, and patients need some proven self-help methods during the long treatment process. In addition, some patients with milder symptoms are eager to help themselves get rid of their obsessive-compulsive symptoms through effective self-help methods. Research has identified “exposure response prevention” as a proven method. Patients learn to expose themselves to stimuli that can cause obsessive-compulsive symptoms, learn to understand obsessive-compulsive thoughts and impulses, and replace obsessive-compulsive symptoms with new healthy behaviors. In addition to the more specialized methods used in therapy, this approach can also be used to learn simpler methods of self-help. Self-help consists of four steps: I. Reaffirmation Patients need to be fully aware of the relationship between symptoms and thoughts, emotions, and behaviors on a daily basis. Because we are not directly acting on the symptoms but addressing the thoughts, emotions and behaviors that produce them. Second, re-attribute. When symptoms occur, tell yourself, “This is not what I want, this is OCD,” and stop reacting directly to the symptoms, setting them aside and doing something else that will help improve them. Learn more about the physical factors of OCD and the psychological factors associated with it, and know that it is an illness, not a fact that you have to deal with. Third, divert your attention. Choose fun activities you enjoy, exercise, listening to music, reading, fishing …… to replace the symptoms. This process is not easy, so you should allow yourself 15 minutes to reconfirm and reattribute. Encourage and reward yourself if the activity is even slightly useful. With constant practice, the symptoms will be greatly relieved. Sometimes your symptom comes so strongly that you cannot replace it with another behavior. You need to keep repeating the above steps while reminding yourself that “it’s not me who wants to, it’s the compulsion that makes me do it, and even if it wins this time, I’ll do better next time.” You need to know that as long as you think this way, you are on the road to healing, even if the symptoms appear. Of course, you need to keep a daily record of your successes in dealing with your symptoms to help you keep encouraging yourself to keep going with your successes, and at the same time this is a continuous process of moving away from OCD. Fourth, re-evaluate. There are two key points in this step, one is to be prepared to endure the compulsive symptoms when they are imminent, and the second is not to blame yourself when the symptoms appear, to be clear about where it comes from, to know how to deal with it, and to refuse to let it defeat you. When the symptoms come, you are ready for them. In addition to exposure and response prevention, replacing old thoughts with a new form of “self-hypnosis” is essential. If you are a compulsive washer, you can try telling yourself repeatedly after each wash that you have reached your goal, “It’s clean, I can go do other things.” If you keep checking your windows and doors over and over again, try to concentrate, carefully and slowly on this task, then stop for a moment to imprint the action in your mind, and finally tell yourself, “I have closed the windows and doors, I see that I have closed the windows and doors,” to be more sure that you have closed them carefully. Repeat it over and over again and be consistent. Give yourself a cue card that prompts you for the time to wash, the number of times to check, etc. Tell yourself that you only need 80 points, not 120. It also allows you to be able to not let your symptoms control you. As a person with OCD, everyone needs to know to enjoy the process of living and working, to not over-emphasize the outcome, to enjoy appreciating the process, to experience your emotions, to deal with the “shoulds” in your beliefs, to know that all of your compulsive symptoms are meaningful to you, and to accept the symptoms until the deeper issues are resolved. All of this is essential to OCD treatment. Finally, it is important to know that you need to make a plan for yourself throughout the treatment process, set a goal that works, and gradually reduce your symptoms without being too urgent, and take your time to see the beauty in your life.
