How do I develop confidence with my stutter?

How do I develop confidence with my stutter? I’m literally trying so hard. Truthfully I don’t care what others think, I don’t. But when I stutter I sweat and get embarrassed. I’m tired of trying to hide my stutter. I keep hiding it by saying “uhm”, pausing until my throat unblocks, or using other words. I just wanna stutter until I can say it. There’s a comedian that has a stutter called “drew lynch” and his confidence is literally unbelievable https://youtu.be/TMDy9ovY7JA https://youtu.be/zp0TJSyLX40 Like I just can’t figure it out. How do I get his confidence? I don’t want my stutter to go away, I want to have the confidence to not care
