What are some jobs that don’t require a cash register ?

I know how to count back change but just the thought of doing it gives me anxiety I think I low key have dyscalcia however you spell it and when I’m counting back change to people it’s like my mind freezes and I get really nervous and I don’t want to embarrass myself if I end up getting a cashier job and this happens smh 🤦🏽‍♀️
