Patients with depression may show that they are at a loss, seem out of place with others, do not like to interact with others, suddenly feel no interest in the things they used to like, like some sad stories or movies and dramas. Patients who like to live behind closed doors and have memory loss, especially recently, loss of appetite, reluctance to communicate with others, insomnia, weakness, etc. must go to a regular psychiatric hospital for a depression scale examination if they have a score of 53 or more, suggesting that depression has appeared and must be treated promptly. Patients with depression generally have “three lows”, “three sins” and “three no’s” Three lows: depressed mood, reduced interest, reduced pleasure Three selves: self-blame, self-sin, suicide Three no’s: hopelessness, helplessness No sense of value
