Yes. Its embarrassing for me too. I have felt that I have highs and lows in stuttering. When im at low, i can speak fluent and interact without any hesitation. But when im at high (still figuring how not to go to high), im lucky enough that my profession includes wearing a mask, so just by wearing a mask I can avoid facial movements while im stuck, then after taking a deep breath and focus on saying it again, Mostly it helps.
