Definitely. One time at school I was having trouble getting the kids to do the work (they were *****ing about how it was boring) and finally one kid threw a muffin at me and I had to leave and run to the bathroom in tears. If I hadn't been severely depressed at that time I would have just gotten pissed and kicked the kid out of my class. It was embarrassing because the last thing you want to be perceived as at that job is weak. I cried for like a half hour in the staff lounge.
