"Anybody else suffering from S.A.D."
Yes.  

I don't know how I'm going to make it through this winter.   It seems like this winter started in October, we've had the heat on since then and there hasn't been much sunshine.

I'd wish we had enough to retire to Florida or south Texas.  I'm pretty sure that I'd live healthier and longer, but more importantly I'd be happier.  When the sunshines I get stuff done.  I love working outside or in my outside shop with the doors open.  This time of year I am cold and my shop isn't heated so any work is limited to a hour or so before my feet and fingers are froze.
