I rarely get blocks but when I do they usually turn into a stammer. But my worst case scenarios are when I try to force it out and by the time the word has been said I am out of breath and need to audibly inhale to keep going in my conversation. Idk. It’s like my brain shuts off and whatever happens happens until the word comes out and I can’t control my breathing. I do notice that when that happens my anxiety is thru the roof. Idk. Lotta things going on at once.
