>"Anybody else ever experienced anything like this or have any ideas to why it would happen?" Yes absolutely, stress could have been the initial trigger at age 28. As to why? Whenever you are in a stutter situation, do you ask yourself 'what is triggering 1) my panic 2) losing my confidence?' In this situation what unhelpful thoughts and behaviors do you experience? (like, it won't work, I can't do it, I need something else, I first need to do something, I don't know what to do etc etc) or do you behave differently with other over-reacting or overthinking?
