I can't say I've had this happen to me, but it sounds like you have a problem in your life that you're unable to deal with by yourself. Since I'm in therapy and making good progress, I'd suggest that you find a therapist and lay this all out for him/her. You're probably right that "the ability to generate a lie and believe it into truth has also given me the ability to take the truth and convince myself that it did not happen." A therapist will be able to help you sort this out and determine if it's a condition or not, and how to deal with it. Sending good thoughts your way ...
