I really wish i had a solve all answer for you but if i or someone else did then this sub would be just a bunch of people that USED to stutter. Practice practice practice! Word substitution is great as well. Finding words that mean the same that are easier to say. Another great one is and I know it's hard to do but don't put so much emphasis on having a stutter. YOU have to live with this issue not anyone else and the more you can ignore the responses or impatience of some the smoother you'll find yourself to be. Never stop practicing! Being comfortable with yourself can improve how comfortable you are with others. I've found the people here on this sub are very supportive and we all got your back
