How do you get over a frustrating few days at work?

Like my job idea and the job itself is easy. But there’s so many suck up’s and snitches there that it gets unbearable. But I fortunately have a couple friends that don’t participate in all that. The other day it just reached a peak and it’s not even like I’m doing anything or my friends are it’s things like “you were seen talking to so and so” like because it’s the slowest day of the week. But how do you get over bad days or few days?
