At school and at work I'm usually unnaturally happy. I wonder if that is just me using the self defense mechanism, reaction formation, to make sure no one really knows how I feel inside. I don't like talking about my problems, maybe it's because I don't want people to worry about me, or make them feel uncomfortable. I know that if everyone perseves you as happy, then it is a happier mood all around, but once someone feels down or unhappy, everyone else sort of follows that mood. I learn that from my friends....
