Self-therapy is very important in the recovery process of OCD. Without the active participation and comprehension of the self, relying only on medication and passively receiving psychotherapy is often ineffective. For those patients who have good self-awareness, i.e., who can recognize their obsessive-compulsive symptoms, who can realize that their obsessive-compulsive thinking and behavior are excessive and unreasonable, and who are willing to change them, they can take their own initiative and actively participate in self-therapy. First: strive to recognize the symptoms as obsessive-compulsive symptoms when they appear. Second: Learn to treat your obsessive-compulsive thoughts correctly and not just suppress them; when they appear, maintain a permissive attitude and try to reduce your reaction to them, such as reducing the corresponding compulsive behavior; you can do something meaningful to divert your attention from them. Third: compulsive symptoms have deep-rooted psychological causes, learn to think and understand, to find out the difficulties, conflicts, interpersonal conflicts in real life and the weaknesses of their own character, to encourage themselves from many aspects, to gain psychological understanding, and to promote the maturity of the mind. Fourth: Build up confidence in recovery. With the help of psychotropic drugs, psychiatrists, family members and especially your own self-growth, recovery from OCD can be achieved.
