I totally know what you're describing. That has happened a few times to me at work and I still cringe remembering it. I know it affected my position at work, and my relationship with my coworkers. But looking back, I made the situation worse by withdrawing and not talking to my coworkers. I think if I would have joked about it later that would have done wonders for how I get along with coworkers and how I perceive myself. Basically I can be my best friend or my worst enemy. That's so easy to type out but much harder to live out.
