I realize my stutter is not forward moving....

I realize my stutter is not forward moving.... I have blocks and I linger on one word long over drawn pauses before I say it out. It’s anything because it takes for even to get my thoughts out and when I approach a word I think I’m gonna have issues on I feel that tension start to escalate I dint know it’s my anxiety because when this occurs my chest and throat tenses up like I can’t breathe or not probably breathing before saying the word I want to say. I realized when I’m relaxed and well rested I dint blocks as much I guess my stutter is not typical as a normal stutterers would be because I dint repeat sounds/words I block on them and pause
