You might have an unexpected (and perhaps even a tad bit embarrassing) emotional reaction to something that is seemingly innocuous today, but so what? Don't suppress it. You need to let your emotions come out in full force right now. Show people that it's not such a bad thing to have human emotions. You can't be a robot all of the time. Celebrate the fact that you are in touch with your feelings -- it is a strength to show them, not a weakness.
