Yes had the same experience recently as well. I think we have similar timelines. I am 26M and this is my 12th year stuttering. Before that I don't remember stuttering bit I used to be anxious when speaking in public. Anyways, I also have blocks but I am angry at myself for being a coward trying to hide my stutter or avoid the situation. So I tried to be brave and push through my block which resulted in repetition, forced sound and uncontrolled volume and pitch. This made me more embarrassed and as a result have gotten worse
