I think I've made contact with an actual Brood Xer

I work as an insurance broker, selling home & auto insurance. I'm sitting in my office going about my day, just got off the phone, and the next second there's a terrifying buzzing sound right outside my ear. It's about 12 inches from my face and honestly 1-2 inches from my left ear. It's flying erratically, at a 45 degree angle to the ground going right for my head. I've got my right hand over my left ear as if trying to protect myself from a lightboxing. I'm ducking, weaving, and moving to the right, away from the bug. I'm screaming like a little girl.<br><br>I finally manage to compose myself, realize I'm in my office, and that at this point it's right next to my head on the drywall. I slowly move my hand in its direction. It lets out a loud buzzing as if to warn me to stay away. I'm able to swat at it twice and finally kill it.<br><br>Third one I've killed in two weeks. First one from work. <br><br>Edit: Pics in comments
