Internet questionnaire survey shows that more than 80% of netizens think they have depressive tendencies. In fact, most people’s emotional state is very good and stable, and the answers of netizens are obviously exaggerated. Of course, there are inevitably people who encounter all kinds of troubles, or get upset or sulky. So, is having these emotional experiences even if there is depression? To clarify this topic, let’s first introduce two concepts: emotion and state of mind. Emotion is the subjective experience of something objective. For example, if you are happy when you encounter something good, or angry when you encounter something bad, these transient sensory experiences brought about by specific reasons such as happiness and anger are emotions. The state of mind is the background, background color or tone of emotion. It is a relatively stable and lasting emotional state that is not very strong. For example, some people may feel that they can see everything well for a while and have energy for everything, so it can be said that they are in a good state of mind. Of course, even if the state of mind is very good, there will be happiness, anger and sadness. In other words, emotions are specific, transient and distinct, while the state of mind is persistent, stable and relatively hidden. Depression, in essence, means that a person’s “state of mind” is low, rather than a momentary “mood” depression. In the field of psychiatry, the criteria stipulate that depressive episodes are predominantly depressed, disproportionate to their situation, and can range from moping to grief. The diagnosis requires at least four of the following nine items on top of the depressed mood: loss of interest, no sense of pleasure; loss of energy or fatigue; psychomotor retardation or agitation; low self-esteem, self-blame, or feelings of guilt; difficulty associating or reduced ability to think; recurrent thoughts of death or suicidal or self-injurious behavior; sleep disorders, such as insomnia, early awakening or excessive sleep; reduced appetite or weight Significant weight loss; decreased sexual desire. While meeting the number of symptoms mentioned above, the patient’s work, life, and interpersonal interactions are affected, which can cause pain or adverse consequences, and this state lasts for more than two weeks before a depressive episode can be diagnosed. Among the 9 criteria of depression listed earlier, sleep, appetite and sexual desire are involved, and these physical symptoms are often easily seen as complaints of physical illness, thus missing the opportunity to see a psychiatrist in the first place. In fact, patients with depression may have physical symptoms in addition to the many adverse emotional experiences described above. For example, poor appetite, headache, throat discomfort, back pain and other feelings. Therefore, after the appearance of physical symptoms, if no obvious abnormality is found after examination, and if it is accompanied by low mood, then it is important to go to a psychiatric clinic. After the onset of depression, a psychiatric evaluation can be conducted at a psychiatric professional institution to determine the severity of depression. If the depression is mild, you can undergo psychotherapy and encourage yourself to exercise actively. With self-adjustment under the guidance of a doctor, depression is expected to gradually decrease. If, after assessment, moderate to severe depression is reached, medication should be preferred. Many new antidepressants are now available with fast onset of action, few side effects and reliable efficacy. Relief is usually achieved within a few weeks. However, maintenance therapy is necessary, and premature medication reduction carries a high risk of relapse. Some patients have concerns about the medication, fearing its side effects, and refuse to take it and insist on self-adjustment. Other patients attribute depression or to environmental factors. In fact, if the degree of depression is heavy, then self-adjustment is almost like “i-top crossing the river”, the power of the self is already very weak and it is difficult to save oneself. The effect of psychological counseling will also be relatively short and limited. Insisting on refusing medication will keep the patient in an emotional gray area for a long time, and the quality of life and happiness index will be greatly reduced. Some people abroad have referred to depression as a psychological cold. In fact, depression is neither like a cold that can be cured without treatment, nor do you want to stop taking medication when you get well like a cold. Depression needs the guidance of experts, the help of drugs and their own salvation, and requires the cooperation of the trinity, not hard to carry.
