Why worry so much about your stutter? Just work on it by yourself and look up ways to get better. If it doesn’t work, find different ways. I don’t think you should waste money on trying to have other people know how to fix you because they don’t know what it actually feels like. The stutter is what makes me a person, and I’ve gotten good enough at not stuttering just from the internet, I don’t care if I stutter about once every couple sentences. I mean I have bad days but everyone has bad days.
