Maybe look at it this way. You have an imaginary joint in your mind (your mental 'shoulder'). This joint has at least 10 muscles attaching to it. Every single of this muscle is a domain if your life influencing the movement in this joint. Let's say the subscapularis muscle is very strong here; this is your anticipatory anxiety. The other muscles are like the domains of self-confidence, vocabulary, fluency etc. So any time you try to make a certain 'movement' with your mental shoulder (aka saying certain things), you make a juttery movement as the balance is complete off. Your 'relaxation muscle' is small, atrophic, weak and its timing is off. So anytime you even want to activate it, it just won't work because it's weak. And the mind works just like your muscles (as it's your mind that activates your muscles directly), especially in joints with many possible movements like the shoulder and the hip. This means you need mental physiotherapy just as if you've had an injury. You have to very slowly and carefully build up the strength in your relaxation and fluency skills. Same for the self-confidence skills etc. First learn how to relax in general. Meditate, exercise, and focus in doing body scans where you learn to relax every single muscle in your body. This is also a complete new skill to learn. This means in the beginning you won't even feel some muscles being tight, just as most people can't move their ears the first time they try. Also focus on your shoulders, neck and throat. Try to relax them and feel the emotions associated with them. What is VERY important with this is that it might make you feel bad and could possibly make you avoid this region or your emotions in general. Remember this litteraly is the cause for stuttering for 95% of stutterers. It's avoiding the fear (which is another layer of fear) that breaks down a normally complete automatic process. Furthermore, as the process above is a very emotional process, more than it seems in the beginning, work on the emotions that cause the insecurity behind stuttering. Of course, the stuttering itself causes insecurity, but it's the wrong level on which you should focus the larger part of your time. It's like focusing on putting bandages on your knuckles while you keep hitting the wall with them yourselves. Focus on both, but more on the layer behind it. Learn why you started stuttering. Learn why you have trouble really showing yourself. Practice more talking to yourself. Accept that you'll feel like an idiot practicing talking again like you're a baby. But fuck it, you're now a baby in this regard, but an expert in future empathy for other people and in adult meta cognitive skills. You'll learn to talk fluently in time. All of this might make the stuttering in the beginning worse as the insecurities behind all of this come more to light. And in the beginning it's difficult to pay attention to all these things at the same time. This is also something you'll learn by practice. It's why I made the shoulder comparison. It's like learning a new movement. You are learning all the new muscle contractions at a coordinated fashion at the same time. It just takes time. Now you're learning to become relaxed and then talk, instead of having the automated response of tensing up. Hope this helps you. Good luck
