I started a new job and it’s making my anxiety spike, idk what to do

I started a new job and it’s making my anxiety spike, idk what to do So I’m 20 and I’ve wanted to be a bank teller for about a year now, I finally got a bank teller job and I love the job itself, but I have a stutter which is making this harder than I thought. I can do the in person banking and even phone calls (which I was most worried for), what is tripping me up are the drive thru transactions. Something about them makes me so anxious and as soon as I hear one come in my stomach sinks because it makes me so uncomfortable Wednesday I had a horrible stuttering fit while trying to help the customer in the drive thru, and my coworkers noticed and made jokes about it (they don’t know I have an actual stuttering disability) and this has made it so so SO much worse. Even when I clock out/on my days off I’m still anxious to go back because I’m so worried about screwing shit up and idk what to do. I’ve (kind of) conquered the fear of stuttering on the phone at my job, but now it’s with the drive thru and idk what to do. I wanna do this job and I can’t let me stutter/anxiety define what I do, but this is the most anxious I’ve been in a long ass time. If anyone has advice let me know, I feel like I have 3 options 1: power through it and hope it gets better with time 2: ask my mom for advice. She has anxiety but she doesn’t understand social anxiety or how it feels to stutter, so she may not empathize with me or understand what I’m dealing with and tell me just to keep pushing through it 3: tell my manager my struggle and ask them for advice/any accommodations. The issue with this is i’m admitting I can’t do the job I applied for which they aren’t gonna be happy about
