I have obsessive-compulsive disorder. I do things again and again. I always feel that if someone says no, something will happen. What should I do?

1. Obsessive-compulsive disorder (OCD) is a mental illness. Cognitive behavioral therapy is considered to be the most effective psychotherapy for OCD, which mainly includes thinking blocking and exposure reaction prevention. Thinking blocking method is to block obsessive-compulsive thinking by diverting attention or applying external control when patients repeatedly have obsessive-compulsive thinking, such as setting alarm bells and relaxing training to relieve anxiety when necessary. Under the guidance of therapists, exposure reaction prevention encourages patients to face all kinds of situations that can cause compulsive thinking step by step without compulsive behavior. For example, if the patient is afraid of being dirty, he should wash his hands repeatedly to ensure that he will not get sick. In the prevention of exposure reaction, they need to touch their sweat, soles, door handles and toilet seats step by step in several treatments without washing their hands, because the things that patients are worried about will not actually happen, and the anxiety accompanying the symptoms of obsessive-compulsive disorder will be alleviated until it subsides after many treatments, thus achieving the effect of controlling the symptoms of obsessive-compulsive disorder.

Second, the onset of obsessive-compulsive disorder is related to the imbalance of various neurotransmitters in the brain, mainly manifested as the disorder of 5- hydroxytryptamine system function. At present, the anti-obsessive-compulsive drugs used are all antidepressants, which are characterized by regulating the function of neurotransmitters such as serotonin in the brain, thus improving the symptoms of obsessive-compulsive disorder. Selective serotonin reuptake inhibitors (SSTIs) are mainly used, including fluvoxamine, paroxetine, sertraline, fluoxetine, citalopram and tricyclic antidepressants.
