Someone was tested on a depression questionnaire in the hospital, and the results showed a high score. The checklist stated "severe depression", and immediately thought they had severe depression. In fact, the meaning of "severe depression" and "very severe depression" is not the same. A similar situation is when someone searches for a depression questionnaire online and finds out how many points their score exceeds, causing them to break out in a cold sweat and think they have depression. Therefore, it is very necessary to distinguish between depression and its symptoms. The common online depression questionnaire measures depressive symptoms, and a high score only indicates a relatively high score for depressive symptoms. People often think that depression is a bad mood, but in fact, a bad mood is just one of several symptoms of depression. This misunderstanding is difficult to eliminate for a while, because the first recorded word "depression" in Chinese came from Bai Juyi's "Yu Yuan Jiu Shu". At that time, Bai Juyi, who was demoted as the Sima of Jiangzhou, mentioned "confusion and depression" mainly to express his emotions. Drawing: When a poet uses words borrowed from medicine, some misunderstandings may also be inevitable. At present, the symptoms of depression are mainly divided into four categories. Firstly, in terms of emotions. Depression actually corresponds to a set of emotions, including not only sadness, but also feelings of guilt, failure, and punishment. Depressed people often have a low evaluation of themselves, which can easily negate their own value and lead to a sense of failure. Sometimes some patients may not be good at expressing their emotions, thinking that they have "no problems in life," but their low mood can be inferred from being prone to tears or a series of sighs. The self blame of patients with depression may sometimes deviate from reality, such as believing that "they have committed a great crime and are sorry for their family", and even believing that "their own existence may affect the appearance of the city.". Irritability is also a common emotional symptom of depression, which is more pronounced in children and adolescents. Secondly, the symptoms of depression are also reflected in the cognitive aspect. Such as suicidal thoughts, health concerns, slowed thinking, difficulty making decisions, and a sense of hopelessness. Suicide is a very important issue, and among the population aged 15-34 in China, suicide is the leading cause of death. In addition, among the elderly population in China, the suicide rate is even higher than that of the young population. When someone commits suicide, people often ask what they had experienced before committing suicide. In fact, no matter how extreme an individual experiences an event, it does not necessarily mean that the person experiencing the event will commit suicide. One of the common causes of suicide is depression. Health is indeed something that every one of us should care about, but excessive concern about health can have an impact on our lives. The cognitive symptoms of depression may also include difficulties in memory and attention. They have selective attention and stronger memory abilities towards content that triggers negative emotions. The lack of hope is also a characteristic of depression, and this sense of hopelessness not only points to the present moment, but also includes the future. In psychology, there is a term called "tunnel vision". In other words, they seem to be following the direction where the light cannot be seen
