We all have ego's. Maybe not the ego we normally refer to which is the part of us that protects our personal reputation, but the psyches executive and principle decision maker. When a person is in a stressful situation where they feel in danger, our ego functions by contending with these outside-world threats with the use of defense mechanisms. Defense mechanisms are unconscious maneuvers intended to minimize anxiety. I know I use defense mechanisms very often. If I fail a test, or don't do as well as I thought I should, I get super upset but then revert to defense mechanisms by acting like it never even happened (denial). I'm curious as to which defense mechanisms work better than others. In other words, we use defense mechanisms to self-protect from harmful situations, but I've always been taught that not confronting your problems only makes them work. I wonder if excessive use of defense mechanism or overuse of a particular one has many negative side effects?
