When in therapy sessions with my Dr. Bill, in the past I've asked him why I still have urges to go back my game or engage in gaming behavior even though I don't want to. One time he responded with this:
"You aren't actually missing fake things, though this could function as a mantra for you. This is the urge of the return to the addiction that happens in all addictions, whether it is hunger for a cigarette, a drink, or a turn at the craps table. It is a neurological siren call and not a moral failing so try not to take the content too seriously. If you need a mantra to resist it, you can say 'I am no longer attached to fake things. I am real'. Very few addicts feel freedom when they interrupt their addiction because they are confronted with the feelings that they were using the addiction to avoid."
"Even when you think it's about you, it's not about you." Dr. Bill
