You need to be getting used to speaking around people, not just speaking to yourself. Stuttering (at least imo) is caused because the brain it trying to concentrate on too much st once - body language, facial expressions, what you know about the person's personality, other people in the vicinity, then the actual stutter What worked for me is just meeting a load of new people all the time and eventually stopping caring about stuttering at all. I still stutter sometimes, but I don't gaf anymore. You'll get there, buddy
