Dear Self,

Dear Self,
You're being grumpy.  Stop it.  You have no valid reason to be grumpy today.  You are not pms-ing.  You do not have pressing deadlines that you're scrambling to meet, or other overwhelming stressors.  No one peed in your porridge this morning.  You're just being pissy.  Get over yourself and get on with your day.  I promise it will make you much happier.
Love,
Me
