What do you do when you hate the career you choose

I have a degree in hospitality. I don’t mind that it’s face paced and can be chaotic. But I can’t deal with angry people. I know there’s some people who just won’t be happy but I just can’t let it go when someone gets mad and yells at me or throws a fit even when I know they’re being an asshole/ dumb. It consumes my thoughts for so long afterwards and it destroys my mental health. But I spent all this money on a degree and I can’t afford to go back a second time for an entire other one. I don’t know what to do.
