Of course, catastrophic thinking is a form of rumination. Your boss throws off a comment that you perceive as a slight. The rear part of the DMN spins into overdrive, looking back at what she said, taking it apart, wondering what you did to deserve that. Was it really a pointed dig? Then you beat yourself up, thinking back, ruminating on what you might have said or done to provoke the comment. You take apart every imperfect thing you said or did at work, reliving the embarrassment. There’s more than enough angst to go around.
