It gets better when you learn to accept it. Trust me it’s hard for me to accept it. I also have days where I’m fluent and days where I struggle, those days usually get me down. The best tip is to just stop giving a fuck, forget them and stutter away. It maybe be cliche but that’s the way I get through it . If I stutter oh well I still think I’m cool in my own way. I play music, I’m fit, I provide myself good shelter/food without anybody’s help, I work hard, I’m a good person to others… I think about the great qualities I have in my head. I tell myself yeah I stammer a bit but I bet they can’t play this song on guitar or I bet they can’t beat me in a race. There’s things that some are better than others and that’s what makes us unique . To get better is to learn to love ourselves. Shout out to all my stammerers, don’t let them treat us like we’re less than them or incapable. we got this!
