When you proudly say "I have obsessive-compulsive disorder", do you really understand the term in your mouth, and do you really know the pain of patients with this disease?
Did you know that the meaning of this sentence is equivalent to the concept of "I have a mental illness".
The author has a relative and friend who suffers from this disease. I will use her as a prototype to create a real life state of a patient with obsessive-compulsive disorder, with reality as the mainstay and fiction as the supplement. Everyone is welcome to discuss it together.
