I’ve stutterd my whole life

I’ve stutterd my whole life Ever since I was 5 I’ve had a stutter it’s been something that’s held me back for a long ass time a month ago I got my first ever job where I talk to people every 30 seconds I’m a cashier at an airport I was scared as shit to do this job. Man I’ve never been so confident in my speaking it’s crazy My only advice is to get out of your comfort zone stop being so damn scared to talk to people if your like that it’s always going to be the same get out of your comfort zone I’ve researched for years how to get rid of a stutter and nothing has worked this is my only fix
