Work anxiety

So i recently got a job as a cashier at this one store thats in Michigan. It's not my first job. I had a job previously at dollar tree as a cashier and stocking. But i started to realize how much stress and anxiety this new job puts on to me. Even tho i am new i know there is other positions such as deli and bakery. And i am thinking about asking to be moved to bakery. Is this something i could do or advice on what i should do? I don't want to constantly go into work feeling anxouis and being a nervous wreck and risking the chance of having a break down.
