I'm not sure what this is, but I have these days where I just can't talk. It's not that I'm trying to be rude. I'm not mad. I just feel shutdown. My coworkers don't understand and think I'm a jerk. I don't think I've said more than four words all week. And I'm not even sure why. I just feel like a robot, like I'm just doing my work, in silence and then I leave. I can't talk, my brain won't let me. I feel it's some sort of avoidance. Does anyone else get this?
