Where did the Sun go?

My mood has taken a turn for the worse.  I would like to attribute it to the fact that I have barely seen the sun in the last few weeks due to the many winter storms going through my area.  However, I’m not sure if that is the cause of my bad mood.  I have started taking Vitamin D supplements just in case it was a vitamin deficiency.   I have a large number of deadlines coming up and can’t let this slow me down.  So far, my medicine has kept my seizures under control.
