24 y/o here. If your stutter is mild, just remember that most people have more important things on their mind than you taking a few extra seconds saying something. Even when I have a noticeable block, people are prolly only gonna remember it for a few seconds and then move on to thinking about class/work/taxes or whatever normal people think about. Once I realized all that, my life also became much less about my stutter and more about other things.
