The general public’s fear and misunderstanding of psychiatry and discrimination mainly come from the perception and feeling of severe mental illness, as long as the mention of mental-related problems, involuntarily associated with the image of crazy, pimply face, crazy talk, eat shit and urine, etc., thus avoiding treatment, so that some mental health and even mental health problems are not dealt with in a timely and appropriate manner. And severe mental illnesses are delayed due to the lack of self-knowledge of the patient, refusal to seek medical attention, and the family’s mistaken belief that they should not seek treatment, thus delaying treatment.
