be sick to death of (someone or something)

To be or become exceedingly wearied by, bored of, or exasperated with someone or something. I'm sick to death of doing my boss's errands. If something doesn't change soon, I'm going to quit! I was all gung-ho about this graduate program when I first began, but I must admit that I've been sick to death of these boring lectures lately. I know you're sick to death of my parents, but they're only here for a couple more days, so try to be nice, OK?
