Yeah ik how that is. I used to stutter lots but i overcame a lot of it.. Do to not giving a crap about what others thought of me lol. If i got tongue tied I would just stop breathe and say it again lol .. I only had a big flair up with people who would idk how to say it like if people would cause my energy to shift so to speak I would have flair ups.. Like my parents uyy they were the worse whenever I would speak normally they be like " huh, we cannot understand you when you speak like that" and I swear I spoke so clearly.. but they would make a big deal whenever I got tongue tied and always interrupted me whenever I would try and speak so idk I guess I became intimated. over the years I put myself in uncomfortable positions and talked in different accents and voices just to keep myself sane lol all in all I have found that triggered enough most people will get tongue tied and its nothing wrong with it. I do believe it's all in the mind as well since most of my episodes came from people that would corner me or make me feel uneasy
