Do you think fight or fight response play a critical role in stuttering?

Do you think fight or fight response play a critical role in stuttering? As we all experienced, when we have a block, we feel nervous and tension in our chest, right? In my opinion, our brain treats negative feelings and bad experiences with stuttering in the past as threats. It links them to potential dangers that can harm us in a negative way. For example: - If I can't perform tomorrow's presentation well, then I may lose my job. Without a job, I'll become a loser, with no money and respect from other people. - If I talk to a girl/boy with blocks and repetitions, I'm less likely to become their potential friend/wife/husband in the future because lack of confidence and the ability to handle social situations. Although these thoughts may not be clear in our mind at the time we speak, I believe they exist in our subconscious and can kick-start the fight or flight response, which releasing adrenaline and cortisol. So what are your thoughts on the relationship between stuttering and the fight or flight response? Do you think they are constantly connected?" And if it is, how to break that cycle?
