One of my coworkers is being overdramatic and baby-ish, and it's driving me crazy. I'm so anxious about what he's going to do next. He gets mad about something stupid and ignores us all, and now he's been packing his office up today because he's convinced they're firing him. Even though all of us have been trying to convince him that it's not happening. I'm so afraid he's just going to quit and walk out, and it's going to screw us all over.
