[Kate*]

I may struggle with criticism, but at least I'm not immature, petty, and passive-aggressive to the point of demoting myself or getting myself fired for being stupid. I assume by now you realize what she's doing, and that you're going to do something about it. Because if not, your boss is always an option. This is someone who didn't have to work their ass off to earn their leadership role, and yet this is what they're doing with it. But, I'm somehow less qualified. Make it make sense!
