You don’t disclose for the sake of the listener. You disclose to trick your brain into doing less work to hide the stutter (hiding it what directly causes blocks). Also, if you are a covert stutter, people do not know you stutter. My godmother was a SLP and had no idea I stuttered bc I was so covert. Keep in mind that people like OP are running away partially because he is unable to say what he wants to say. OP is essentially being forced to lie about who he is. He wants to be able to not care when a listener looks confused/concerned, but there are some very heavy, real things in the way.
