It is often said that “if a man does not have far-ranging worries, he must have near worries”. Indeed, melancholy is one of the basic human emotions, a product of human evolution. Melancholy made ancient man more cautious in the dangerous jungle, avoiding many unnecessary risks and better protecting himself, and melancholy has become a psychological tool to adapt to survival since the day it was created. As the saying goes, “the sky is unpredictable and people are blessed”, when people encounter setbacks and misfortunes, depression is a normal emotional reaction. Such as the loss of a loved one, depression, sadness is a normal response to mourning. But if the melancholy, sadness is too strong, or can not get out of the melancholy for a long time, then it is a pathological emotional reaction, that may be suffering from depression. Depression is a ubiquitous debilitating injury Depression is a group of mood disorders or affective disorders caused by various causes with depression as the main symptom, a group of clinical symptom clusters or states centered on the self-experience of a depressed state of mind, an unpleasant state of mind experience. Depression does not just equate to a whole lot of pain, but too much pain is deposited in the mind and depression tends to strike. While debilitating injuries arise because of melancholy in a certain situation, depression is ubiquitous debilitation. Sadness is like the tumbleweed blown by the autumn wind, which is broken on the ground and rolls with the wind, but rolls bigger and bigger, endlessly. The deteriorating emotions are like ripples blown by the wind, spreading one circle after another. It takes quite a long time for a building made of iron frame to be blown by the wind and rain, to be rusted and even to collapse, but the rust is gnawing and spreading all the time, and over time, the iron frame will eventually collapse suddenly at some point. The same is true for the human body and spirit. Exposed to the ravages of wind and rain day after day, the body and mind are getting weaker and weaker, as if a gust of wind can scrape itself down. The frustration inside is like the rust of an iron frame, accumulating little by little. Why does melancholy always seem to have no end in sight? Boredom is the beginning of melancholy, which colors your day with gray and weakens your motivation until you feel tired, bored and self-indulgent. While it’s hard to pinpoint where severe depression begins, crossing it will lead to a mental breakdown. Happiness is always fleeting and hard to find, while depression always seems to have no end in sight. Even if you understand this, it is still impossible to relax and be happy, while it is much easier to fall into sadness. Sadness and loss seem to be the norm in life, and although this is not a common experience for the average person, it is also the main cause of depression formation. Depression occurs when you care about something that has been lost inside. In the moment of loss, you seem to want to hold on to something, but you can’t, like watching a glass fall from your hand and break. At this point you will find that “joy is no longer so pleasant, and pain is more unexpectedly painful”. There is a Russian adage: “If you don’t feel sad when you get up in the morning, it means you are dead”. Pain may be one of the proofs of vitality, but life is not all about pain and painful experiences. Depression may be the number one cause of death worldwide? According to studies, depression is the leading cause of disability for countless people around the world. The point-in-time prevalence of major depression in the general community population is 10.3% and the lifetime prevalence is 17.1%; the prevalence is particularly high in women, 2-3 times higher than in men. The prevalence of depression is even higher in patients with somatic diseases, e.g. 33-42% in cancer patients, 47% in stroke, and 45% in myocardial infarction. Depression has a significant negative impact on mental and physical health, social interaction, occupational ability and physical functioning of individuals. According to WHO, depressive disorders ranked 5th in the global burden of disease in 1990, and it is predicted that depressive disorders will become the second largest source of disease burden after coronary heart disease by 2020. Most importantly, depressed patients have an increased risk of suicide, self-injury, and even killing their loved ones. 2/3 of depressed patients have had suicidal thoughts and for, 15% to 25% of depressed patients eventually succeed in suicide. U.S. data show that the annual suicide rate among people with depressive disorders is 83.3/100,000, it is 8 times higher than the general population suicide rate (11.2/100,000), becoming the second cause of death after traffic accidents. Worldwide, if we count the factors that lead to loss of health and disability in adulthood, most of the diseases that cause suffering are attributed to depression, with the exception of heart disease. Depression has afflicted humans longer than war, cancer and AIDS combined. The real culprit behind other diseases and problems, from alcoholism to drug addiction, is depression, so that it appears that depression may be the number one cause of death worldwide. Can depression be cured as it continues to spread? Depression is not a product of modern times; depression came with mankind as soon as they started to think for themselves. But depression is spreading in modern times, for some specific reasons. Nowadays this newly sprouted problem has become so obvious that we can no longer turn a blind eye to it, but should try to control them. There is no doubt that the rise in the incidence of depression is the result of social development nowadays. The accelerated pace of life, the chaos caused by technology, the alienation of people from each other, the breakdown of traditional family structures, the loneliness characteristic of the metropolis, and the loss and decline of what once had meaning in life have all contributed to the upheaval of the human spiritual world. Fortunately, we have solutions to these problems; we have medications to choose from and psychotherapists to heal our wounds. Depression is an increasingly heavy burden on our society, but not so heavy as to be irresistible; we have spiritual sunshades and sunscreen. Healing depression requires a rebuilding of the self, love and insight, and importantly, time and our total effort.
