I've searched around online and I can't find anything that sounds like its what I have.
There are things in my life where I've made up a lie, and I begin to believe that lie is actual reality and that's what actually happened. Sometimes I know deep down that's not the truth but i still believe that lie i made up is true. I don't mean to lie, nor do I want to lie, I think it happens when I'm struggling with something and don't want to accept reality, so i make my own reality with the lie as sort of a defense mechanism. And then I have memories of my lies as if they really happened, and actual reality doesn't have a memory anymore.
I'm not a compulsive liar, or a pathological liar. I don't lie all the time or about everything, and I don't make up crazy stories. Only the things I am having a hard time dealing with, and I can't accept that. So my brain creates this other made up reality.
For example: Years ago I was scared to have sexual relations with anyone. It wasn't my nervousness and it wasn't because i wasn't ready. I was just legitimately scared and I felt like it stemmed from something in my past. Like something bad happened to me and thats what my gut felt. Well not liking that I felt like this for no reason, I kind of made up that I had been raped and forced to do something. However I have no clue if it actually happened because I made that my reality... but deep down i know it started with a lie, because i felt really scared. Now I legit believe this happened and I am like this in every single relationship I have, and it holds me back being scared to do anything and telling people its because something bad happened to me before so they won't push anything on me. I didn't mean to make up this lie, I just didn't want to accept that i was scared for no reason.So it was a defense mechanism.
