My experience might be different but I've met a lot of stutterers and they're mostly assholes (hopefully thats not the case with everyone). I have a v bad stutter like saying 1 word in 10 seconds and i knoe a couple of ppl who stuttered pretty badly but are better now. As soon as I get stuck they jump in with tricks like u should do this. This helped me. Its all about confidence, i chose to be confident, u should too etc. They rarely let me finish and just tell me to breathe etc. They can't understand that everyone's stutter is different and what worked for them doesn't work for everyone.
