We've had people right here say they have created stories, exaggerated stories, outright lied, etc. about their history to their therapists. I am guessing they either don't feel their reality is serious enough to warrant attention maybe so they make things "worse" than their reality? Or perhaps with some it really is the way they have learned in life to get attention? Clearly they have real psychological issues that need to be dealt with. Somehow the fabrications are a symptom of another problem altogether?
