Yeah when there is this feeling of anticipating the word that will block, it's like a loss of breath the moment we get to it sometimes. Like we were about to say it and it's lost in a vortex. It's such an odd sensation. I thought the body was practically making sure I don't say it as if my life depends on it and the most fascinating thing was how on command it was, had to be the right situation, the right moment, and even if I tried again, if the right circumstances were still present, the breath would feel like it fell right from under you again. The fascinating thing is it's not the word on it's own because I could probably say it a thousand times over in a different situation like when people order food how it's different depending on what they want at the time and being in that position. I think it's a part of stuttering if that sounds like you can relate to how I described it above. Another example I guess would be when your stuttering and it just takes your breath away after a while where you are tired and feel breathless from feeling you had to force your way through the words. It's all a part of stuttering, at least for me it is and was.
