I've had enough of this
I have endured as much of someone or something as I can handle. I've had enough of this—it's time for you to leave! Is she still making snarky remarks about me? Oh, I've had enough of this.
I've had enough of this!
I will not take any more of this situation! Sally: I've had enough of this! I'm leaving! Fred: Me too! John (glaring at Tom): I've had enough of this! Tom, you're fired! Tom: You can't fire me, I quit!
