Commentor: i think i am a pathological liar. i have no idea why i do it. my brother does it, my dad. for no reason at all. is there any way to stop?
Alone’s response: yes. Decide to stop. Pathological liars fill the void of their identity with words. If the words stop, then the identity is uncovered and subjected to scrutiny. You have to be brave enough to withstand that scrutiny.
It’s like a teenager, who hides in plain sight; who talks, dresses, acts in a manner he believes to be unique and independent, but which is so obviously common to everyone else in his group. It’s all made up, but he feels it as genuine. What matters is that others see and judge the clothes, the words-- so they don’t think to judge the person underneath.
