It's great that you were functioning at your job and held it together for so long, don't worry people crack at work from stress, even without mental disorders. I'm sure they would understand, and this one time won't change their perception of you from the rest of the time you kept composure.

I was manic for 9 months at school and completely embarrassed myself by being a complete spastic. I will never see any of them again but I can't get over it, I feel the need to explain myself to them since they all looked down on me and thought I was on cocaine. It's hard to let go, so I don't mean to downplay how hard it can be. But one isolated incident won't jeopardize someone's perception of you, everyone has a breaking point
