1, cathartic therapy: tell your tension, such as your past trauma and misfortune suffered in a certain situation or at a certain time, and let out your inner painful emotions to the fullest. Saying your fears also reduces your fears, and saying your tensions also relieves them. 2, divert attention: When compulsive symptoms appear, find ways to divert attention. For example, once you go out to check the door lock, you can schedule a tighter time, because the time is tight for fear of being late, after going out attention is on catching up with time is too late to check the door lock again and again. 3, let nature take its course: sometimes it is necessary to let nature take its course. When compulsive thinking occurs, do not fight or use the opposite idea to “neutralize”, to take the symptoms to do what should be done, the actual thing. 4, at the same time, if you can take some drugs with brain nerve conditioning under the guidance of professionals, the improvement effect will be more prominent.
