About depression, many people still have a half-understanding of it. Some people think that a momentary depressed mood is depression and are nervous to seek medical attention, while others think that depression is far away from them and even underestimate its power, which leads to irreparable tragedies. Everyone will be depressed at times, but depressed mood ≠ depression. So, what is the difference between depressed mood and depression? Depression is a persistent, recurrent low mood disorder with two core symptoms: a persistent low mood, feeling sad and mopey; and a persistent decline or lack of interest, or loss of pleasure. This mood usually lasts more than 2 weeks, or several months or more. The difference between depressed mood and depression is that “depressed mood” is not a disease, but an unpleasant, depressing experience that occurs after a specific life event, and is a normal emotional reaction that people are born with. For example, if an object you like is suddenly lost or broken, you will feel depressed and unhappy; if you are suddenly unemployed or frustrated at work, you will feel depressed or anxious; if you feel sad because of the breakup of a lover or the death of a relative ……. This mood is short-lived, through confiding in others, self venting, eating sweets, exercise, sleep, travel, etc. can be self-regulated, generally within two weeks this unpleasant mood will be relieved and recede on its own.

And depression can recur, with the basic symptoms of each episode being roughly similar. Therefore, one should never arbitrarily match various symptoms with oneself. If you have a tendency to depressive symptoms, please go to the psychiatric department or psychology department of a hospital in time, and also contact a professional counselor for consultation.
