The term depression can be used to describe the emotional posture of regular people, but it also relates to a disorder within the scope of mental health. Depression can only be called depression when sadness and despair persist and interfere with the normal functioning of the individual. Depressed mood varies in severity and is only called adolescent depression when it is severe enough to consistently interfere with the normal functional performance of the adolescent. The incidence of adolescent depression has been increasing in recent years, but people are still “unaware of the true nature of the disease”. If one or more of the following signs of depression persist, parents should seek help from a psychiatric psychologist. A. No joy in the face of the goal, the ideal, a smooth path, the patient does not feel joy, but rather sadness and pain. For example, if you get into a famous university, but sad, heavy heart, want to beat the drum. Some of them often run home for no reason during their university studies and want to withdraw from school. The patient is generally younger and does not express emotional problems, but only some physical discomfort. For example, some children often use their hands to support their heads, saying that they have headaches and dizziness; some cover their chests with their hands, saying that they have difficulty breathing; some say that they have something in their throats that affects their swallowing. Their “disease” seems to be very serious, chronic, or recurrent, but after many medical examinations, no problems are found, and after taking many medicines, the “disease” still shows no signs of improvement. Third, the bad implication is mainly in two aspects: one is the subconscious layer, which can lead to physical disorders. For example, once the patient arrives at the school gate, classroom or workplace, he feels dizziness, nausea, abdominal pain, limb weakness, etc. When he leaves this particular environment and returns home, everything is normal again. Another kind is the consciousness level, which exclusively goes to the negative side to guess. For example, the patient thinks that the test results are not satisfactory; he or she does not know how to interact with people; he or she thinks that certain practices are a mistake, or even a sin, causing trouble for others; his or her illness may be “mental illness”, it is really “mental illness” how to do, etc. Fourth, to change the environment may have some conflicts in the school or unit, or for no reason at all, the patient is deeply concerned about the pressure of the environment, often distracted, depressed, unable to study and work at ease, and desperately ask their parents to find a way to transfer to a different class, school or work unit. When they really go to a new place, the patient’s state does not improve, but has other reasons and excuses, and still thinks that the environment is not satisfactory, and repeatedly asks for changes. 5. Rebellion against parents In childhood, patients obeyed their parents’ discipline, but when they reached adolescence or went into society, they not only did not communicate with their parents, but also confronted them in every way. In general, they do not tidy their rooms, throw their clothes around, are slow to wash their faces, comb their hair, eat slowly, and do not finish their homework. More serious manifestations are truancy, staying out at night, running away from home, going over old scores with parents (rough education in childhood, the impact of parents’ divorce and remarriage on them, etc.), and wanting to sever ties with parents, etc. VI. Decreased interest in activities No longer enjoys previous hobbies, no longer participates in sports and other favorite activities, low self-esteem, self-blame and self-condemnation, negative view of one’s own abilities and values, believes he or she is not good enough, significant changes in eating and sleeping patterns, sleep disorders, or overeating. VII. Suicidal behaviors Children who cannot name their inner feelings may express their emotional tension, physical discomfort, inner pain, and too low self-evaluation through suicidal behaviors, such as cutting their wrists or skin. Because this type of suicide has psychopathological and biochemical factors, the patient does not want to die willingly, but is swayed by the disease factors and cannot help himself.
