Do you think a person with social anxiety can become a cashier?

my first day at work is going to be tommorow as a cashier but I'm not really good at communication with people because I'm always self conscious about my looks because I have a big nose and I'm a female. I'm always afraid people would laugh at me or look at me weird (which some do) and that makes me get a bit anxious. I'm nervous that I'm get anxiety being a cashier but I need that money I don't know how to feel
