Recognize this phenomenon of self-doubt?
You are not alone. Although many people suffer in silence (as they do not want to be revealed for what they perceive to be major deficiencies), the syndrome is quite common, especially in medical school. According to one 2016 study, almost a quarter of male medical students and nearly half of female students surveyed suffered with impostor syndrome. The phenomenon can be associated with depression, burn out, and anxiety. The American Psychological Association offers a few tips for overcoming impostor syndrome including speaking to mentors, recognizing what you excel at, and talking to a professional if necessary.
