Dealing with diaphram blocks

Dealing with diaphram blocks Hello I’m 28 and in many situations, I have some blocks, over the time I noticed that I contracted my diaphragm/chest because of anxiety (when I read alone I don’t suffer from issues). It’s not really new because when I was a teenager, I stammered on the words, now there’s no stammer but the words struggle to get out. Really, it emotionally ruins my days, I can’t properly discuss with friends, colleagues because of that. I spent many times dealing with my stutter and even after taking theater class, therapist, subscriptions, it’s still there. Do you have any or recommendations ?
