with a shiver in my bones just thinking about the weather

This is the anthem for all Seasonal Affect Disorder sufferers in the world (including yours truly).  Why is Natalie Merchant so perky while she sings this? 

I see the signs of spring starting, and the snow is gone except for in the shadows, and we've had a few warmish sunny days so I know it's going somewhere...but these last few weeks have been very, very challenging for my mental and emotional energy.  The sky in Ithaca is often a coal grey that sits about 3 feet over your head in a dark smooth blanket.  I am literally working from my bed today, with computer and sketchbook and pot of tea and two cats.
