I'm a pathological lier, and I lie about the stupidest things.

I'm writing this at two in the morning. Sometimes I think about it at night and I can't sleep.I told my highschool friends I have a rare pneumological desease (A1AD, look it up), it's false. They still believe it today, six years later. I've been lying to my college friends about my religion for three years. I've integrated a student religious community when I'm not even baptised (I have very good theological knowledge). I told all these people I have a brother ; I don't, I'm a single child. I also told them I have that same desease. I'm very active in an online community where I pretend I'm somebody else, for almost four years now : there, I'm 20 years older, I have a wife and two kids.I lie to my parents in other way too private to share, but I guess the only fact that I lie to everybody else and that I'm too ashamed to admit it to them is already too much. I lie to them about not lying, if you'd like. I grew up in a loving household, I don't know what is wrong with me, but I guess I feel the need to lie. To attract attention ? To become someone else ?My lies have never been discovered, and I really think I'm not mistaken when I say they might never be. My different social groups almost never interract. When I lie about something, it's something I have extensive knowledge about (I pretend to belong to a religion I know more about than probably most actual believers). But I sometimes feels being different persons eats me from the inside.When I think about coming clear, it crushes me, it absolutly terrifies me. The mere fact I can only talk about it here makes me want to cry. I'm probably not going to sleep, waiting for a comment.EDIT : spelling via /r/offmychest https://ift.tt/3485sb3
