Stutter has gotten so bad that I’ve made myself pass out twice now

Stutter has gotten so bad that I’ve made myself pass out twice now My stutter has gotten so bad over the last few weeks that I am knocking myself out. I get stuck on a beginning sound, I make an almost growling sound trying to force it out. Something in my brain clicks and I cannot stop it. I run out of breath until I am almost gasping and weezing. The couple times I’ve passed out, I get the word out, start to see stars and get dizzy and I fell to the ground both times. Come to a minute later. This is insane and the worst my stutter has ever been in my life
