So bored

I have been in such a bad mood recently. The exam result of the two classes that I teach isn't satisfying. Exactly it's worse than the other two classes. My teaching results has always been the top in our school,but------ I can haedly accept this .The competition among the teachers in a school is very intense. All the teachers know it's bad for our health, but we have to compete with our colleagues.This time I fail, I am beaten.I feel unhappy. But I am also trying to cheer up and encourage myself. And I am trying to find out the reason why I failed .It's the most important I think. I hope something enjoyable can happen .
