I do realize that line by itself looks a little nasty, I'm sorry. I meant it to be taken together with "And we're all frauds to some degree, because we all tell ourselves stories about ourselves that feel good."

How about without using the word fraud, which can be a little more loaded than I intended, I simply stick to the line afterwards– that we feel gnawing pains, etc whenever our actions are not consistent with the beliefs we hold (or claim to hold).
