Talk to me「I don't know anything.」

"Do you want others to call you "mentally ill" or "mentally ill"?"
"The mentally ill!"
"Why do you prefer "mentally ill people"?"
"Subjectively, a "mentally ill person" is no different from a patient with a bad cold, but people call you crazy, which makes me feel that he is scolding me, and isn't a psychopath usually described as a madman!"
"So what do you think is the main difference between "mentally ill" and "mentally ill"?"
