I am a compulsive liar. I often tell pointless lies when telling my friend stories. It started out as me saying the very rare and small exaggeration to make my stories sound better and more interesting, but it progressed and now I’m always adding little details or changing things ever so slightly even if they serve no purpose.
I don’t think my compulsive lying has anything to do with lying out of fear or anything. I have lied out of fear in the past but that is an extremely rare occurrence compared to my compulsive lying which probably happens dozens of times a day. My compulsive lying is one of the reasons I don’t want to go to Confession. I can’t confess stuff that I know I’ll just keep doing again and again afterwards, possibly even on the very same day.
I have a friend who is similar to me but his lies are way more transparent. My lies are usually little things that spice stuff up and while his are often the same, mine sound far more realistic.
As a final note, I’d like to add that this is not caused by mental illnesses or anything like that, it is just categorised as one since something isn’t normal in the brain. It’s just habitual lying that became so habitual that the brain got too used to it. People with it are still at fault for habitual lying in the first place and it’s not incurable if enough effort is put into fixing it.
