Come on, you're smarter than this. That's not Catch 22. It's a Catch 22 when the rule that determines the outcome is outside of one's control--or else, you know, it wouldn't be a rule. An example of a Catch 22 rule is this: "I will only be admitted to a psychiatric hospital if I fill out a questionnaire. In filling out the questionnaire I am deemed sane enough to function. That means, I won't be admitted to a psychiatric hospital whether I fill out a questionnaire or not." Note here that the subject has no control over the rules that govern whether or not he will be admitted, making it an inherently absurd concept."I could solve this problem easily if I could control myself" That's a catch 22 my friend.
So what is the "rule" that is making this a Catch 22 for you? That you can't control yourself? That's a belief not a rule. So at least term it as such ("I'm afraid I can't control myself enough to get better") and don't try to hide behind falsely applied experiments in logics.
