I’m going to say the thing that ALWAYS pissed me off when my dad would say it to me when I was a kid. Relax. I don’t mean that in a glib way. Literally practice relaxing. You sound very mentally/emotionally ‘busy’. The worry you are experiencing comes through very well in your post. Whether that is with physical busy or mental busy, Both exacerbated my stutter. Meditation is a practice and it did wonders for my stutter. There is no cure but learning to calm my mind has made me almost as fluent as someone with out a stutter. If you find it valuable, here is my routine. Next time you lay down for bed, play meditative music or brown noise lightly on your phone. Lay down, close your eyes and just start breathing. 5 seconds in and 5 seconds out consistently. Clear your mind and think about nothing, imagine you are in a pitch black room inside your mind. If your mind starts thinking of things, anything at all, pull it back in to the dark room. Your mind will keep trying to escape the dark room to try to manage your worries and anxieties. You may lose the breathing rhythm. Pull that back in. Keep pulling both back in until you fall asleep. If you just can’t get your mind to stay in that dark room, imagine instead a school of dolphins diving and rising in the ocean to the rhythm of your breath. 5 seconds down deep into the ocean and 5 seconds ascending up to the surface. As you get better at that, while you are in that black head room, slowly start flexing your muscles while you breath. Start with your toes and work your way up. Ankles, calves, knees, fingers, wrists arms, shoulders, neck all the way up to your forehead. Spend a minute or two flexing each one followed by a minute of total relief. Feel how good each muscle group feels after you let it go loose. Do it Every night. During the day if you are feeling anxious and have the time. Even if you are at work or in a meeting. Flex the muscles you can without looking silly :). Spend a few minutes breathing in that rhythmic motion or if you can close your eyes and go to that dark room. With enough practice, these little exercises during the day (slowing your breathing, flexing muscle groups, or closing your eyes and letting your mind go black, can put your mind into that meditative state, bring down your heart rate and decrease the firing of those synapses in your brain. Nothing in my 45 years on this planet has done a better job in helping me live with my stutter. I’d say it is at least worth a try!
