how do you overcome your stutter?

how do you overcome your stutter? I know that stutter is incurable. So I just accepted that I can never be the person I wanted to be so I might as well just deal with it. In a few months, I wish to get a part time job it could be waiter or cashier. But I can’t just seem to overcome the fear of getting made fun of or the disgusted look when I stutter. I can’t even do a simple presentation properly. To those who didn’t let your stutter affect your work life, how did you manage to overcome the fear? I really want to know. Thanks :)
