Self-criticism can be a constructive mechanism of self-improvement and self-reflection, but it also can be very destructive. In the age of social media, we constantly have access to other peoples lives and can not help but to compare. It is all good, until this analyzing becomes more agressive towards one self. For example, 'oh, they are vacationing at such a nice place' goes to 'I am so stupid, I can never earn so much money to afford such a vacation'. Not everyone have a highly developed self-esteem, then this self-criticism becomes hard to handle and can even turn into constant anxiety and even depression. One of the most prominent self-criticizing has to do with the self-image or appearance. People want to look good and also stand out. This balace is hard to achieve. Sometimes people go as far as immitating the 'idol' or the person they think looks perfect. By self-criticizing you are almost denying your personal traits, and wanting to look like someone else. It all comes down to self-acceptance and controling your self-criticizm. If you try to look at yourself more objectively, you will have healty self-criticism that will help you improve.
