If you woke up on the wrong side of the bed, we're here to help.  Here are five things you should know if you woke up in a bad mood today.

#1.)  Talking to a Stranger Might Help.  A study at the University of British Columbia found that even short interactions with someone new can put people in a better mood.

--They think it's because we PRETEND to be cheerful when we're around new people. And just PRETENDING to be happy can make you FEEL happy.

#2.)  Talk to Someone Who's in a GOOD Mood.  Happy people are pretty much the most annoying thing in the world when YOU'RE not happy.

--But a recent study found that both happiness and depression might be contagious.  Obviously not in the way the FLU is contagious.  But being around happy people tends to improve your mood . . . which isn't surprising.

#3.)  You're Better at Spotting a Lie.  Researchers in Australia found that when you're in a good mood, you tend to be more trusting and easier to fool.  And when you're in a bad mood, you're more skeptical.

#4.)  You're Less Likely to Be Superstitious.  That's according to "The Journal of Personality and Social Psychology".  When you're happy, you're more likely to follow your gut, even when it's not rational.

#5.)  You're Not the Only One.  According to the National Institute of Mental Health, 9.5% of American adults suffer from mood disorders, including depression.
