Maybe next time write down your ideas so if you start to struggle you can read and pace yourself better? I tap my forefinger to my thumb when I tLk, I tap to each syllable. I usually say at the start by the way I do stutter sometimes just to put them at ease. Sometimes people have never met a person who stuttered in real life and they shut down because they don't know how to respond. You can always look into a speech easy device. It's expensive, 5k but it works well to a point. Your brain will adjust and start ignoring the device after six months or so.
