Depression, also known as depressive disorder, is characterized by significant and persistent depression and is the main type of mood disorder. The depressed mood can range from sullenness to grief, low self-esteem and depression, or even pessimism and anxiety, and may include suicide attempts or behaviors; some cases have significant anxiety and motor agitation; severe cases may have hallucinations, delusions and other psychotic symptoms. Each episode lasts at least 2 weeks, or even several years, and most cases have a tendency to have recurrent episodes, with most episodes resolving, and some having residual symptoms or becoming chronic. There is a fundamental difference between a normal person’s bad mood and the bad mood of “depression”. A bad mood does not necessarily mean “depression”. Normal people have emotional ups and downs in life, sometimes with high emotions and excitement, and sometimes with low emotions and listlessness. Normal people have good mood regulation function, and their bad mood lasts for a short period of time, generally not more than two weeks, and their mood basically does not affect their social functions (including work, life self-management and interpersonal communication). In contrast, depressed people have uncontrolled mood regulation, and their bad mood often lasts more than two weeks, and the degree is more serious, often affecting their social functions. Some people are more introverted and work under more pressure, will they be more likely to suffer from depression? There are ways to effectively reduce the chances of developing depression. The following suggestions are shared with you: 1. Focus on the present: Think about how to get things done in front of you instead of focusing too much on the past or the future. 2. Change the way you perceive: Replace the negative words you always say, such as “I’m going to fail” and “I can’t do it” with positive and aggressive statements, such as “I can do it. “I can definitely do it” and so on, to encourage themselves. 3, do their own ability to work: do not set too high requirements for themselves, so as not to bring unnecessary pressure and greater frustration, even if they encounter setbacks, should also be seen as an opportunity to learn. 4.Positive expression: When you are lost, try to express your inner feelings, find someone you trust to talk to or cry. 5, brave face: once the problem occurs, should actively seek a solution, do not choose to escape, so as not to bring worse consequences. And, of course, be alert to the possibility of depression! Depression is often manifested in the psychological aspect as a persistent low mood, loss of interest or motivation in many things, loss of pleasure, some patients often feel irritable, worried, pessimistic about the future, feeling worthless, a burden to others, and even suicidal thoughts or actions. In the physical aspect, the symptoms include loss of appetite or weight loss, insomnia or early awakening, loss of libido, fatigue, loss of strength and energy, and slowed movement. If four or more of these symptoms are not caused by a physical or mental illness, depression is a strong possibility.
