Yeah, stutter is strange in general. Everybody is different and have different issues when it comes to stuttering. At least you’re fluent 99% of time, for me it’s different, some days I’m more or less fluent and some days I just hate talking because of my blocks, so I never know what to expect when something comes out of my mouth, which is really depressing at times. Hope you get around your issue in the near future and try not to overthink it as it may make the things even worse. The more you are aware the worse the blocks/stutter gets.
