I would listen to Mrs. Sisskin's 5 episode series on this: http://stuttertalk.com/tag/vivian-sisskin/. I confused acceptance with acknowledgement for a long time too because I thought I had already accepted the fact that i stuttered and it didn't need to be a problem, but i was merely acknowledging it. You can't really "convince" yourself that it's ok just like you can't gain confidence by telling yourself that you're great and be more confident. You're changed through your actions. Listen to the episodes, that's the best place to start imo.
