Specifically, my emails got the better of me.

Today's Lesson: Trust No One.

Don't send emails to your boss asking something to be kept confidential because it just won't happen. Don't ask to be allowed to talk to him/her in confidence because there's just too much bureaucratic crap to wade through for that to be feasible.

Keep all your feelings inside until you think you're about to explode.

Otherwise, you might just lose your job.
