Similar story here. General pattern I’ve observed in people, but especially people like us:

The slings and arrows of this world somehow cause us to believe a lie; and in this belief we act in a way that somehow impacts us negatively and in someway at least partially reinforces the lie.

My advice: find the subtle agreement with falsehood you’ve made. Find the agreement with the lie and choose not to believe it.

They say two things about the devil: 1) he’s a liar and 2) the greatest trick the devil ever pulled was making everyone believe he doesn’t exist.
