My manager just let me go home early

It's obviously Saturday so it's busy. I spent my break crying instead of eating my food in front of half the restaurant because our break table is right by the bathrooms.

I'm mostly just writing this to get it out. I just feel like I fucking suck at my job if I'm literally breaking down after a few hours of busy weekend lunch. I want to be able to do this but when I'm overwhelmed I honestly feel like I should just fucking quit and use my degree at some easy office job. I'm not even bad at making the damn food I work at a fucking chain for crying out loud it's not complicated but I still just don't know how to handle the stress right now and I'm just feeling really stupid and weak

I don't know maybe someone here has stories of getting past these feelings
