say you're addicted to doing X (X could be an external or internal behavior).
1. you "believe" that X will make you feel better. believe is in quotes because you haven't really looked at it yet; it's more of a reflexive belief.
2. you recognize that X actually doesn't satisfy that deep craving for something that it was supposed to satisfy. in fact, you may recognize that X even makes you feel bad. but you keep doing X because on some level you don't apprehend how it is hurting you.
3. you internalize and integrate the realization that X makes you feel bad and doesn't relieve your emptiness.
