What does it mean to accept a stutter, and how can I do it?

What does it mean to accept a stutter, and how can I do it? I’m 20 and I’ve had a stutter my whole life, it’s a very mild stutter but that is partially because I’ve learned my own tricks to help with it, and I’m really good with masking. Most people aren’t even aware I stutter until I tell them or they’re around me for awhile. But it gets bad when I’m anxious I just started a bank job and I have to answer phone calls and use specific words here which is gonna be hard and makes me anxious. But besides that I wanna be able to talk freely, I avoid certain words when I talk, I barely talk to people in public, and every time I stutter I feel my chest get that anxiety feeling and it sucks I wanna know what it means for you guys to accept your stutter? How do y’all talk without the anxiety when you get caught up? When I try to freely let myself stutter instead of hiding it, I focus on it and stutter a lot more because I’m focused on it. When I speak I know I look unconfident when I get caught on words, I wanna be able to feel confident and look confident even when I’m stuck. How do I do that? I just can’t seem to accept myself
