What is the psychology of people who blackmail themselves? Why do so many people like to shame themselves?

Being self-deprecating and talking about one's shortcomings are two different concepts. The former is self-confidence and the latter is inferiority complex\x0d\\x0d\For example, Obama once said at a dinner party, "Eight years ago, I was a "Young guy, full of idealism, full of energy. Look at me now, in just six months I will officially become a 'lame duck' president." This is self-confidence, not afraid of others knowing your shortcomings or shortcomings. Dare to reveal and face your own shortcomings, and be accepting and calm. This is a healthy psychological activity. \x0d\\x0d\To put it another way, eight years ago I was still a young man, but now I have become like this. There is no more behind. This is complaining, low self-esteem, not daring to face oneself, not daring to face reality, not daring to accept one's own problems (so-called shortcomings). Although I say it out loud, the psychological activities in my stomach are completely different, because The most fundamental difference between inferiority complex and self-confidence is the difference in concepts. \x0d\Extended reading:\x0d\Self-deprecation is a hot word on the Internet, which means self-deprecation. \x0d\Speaking of self-destruction, both male and female stars are fond of making pranks and "destroying their image" sometimes! \x0d\Self-deprecation means self-deprecation. Self-defeat is both a state and a way of communication. Self-mockery is also a kind of self-release and therapy under pressure. \x0d\To put it simply: you laugh at yourself and harm yourself.
