Sometimes I long for the sun after a bunch of rainy days but as far as winter doldrums I do not really get them. I look forward to snow (though we have not really gotten any) and beutiful sunny days that reflect the light off the snow making it look clean and magical.
I think I get more down from day after day of cloudy, overcast, rainy weather. I love the sun and light it makes me so HAPPY and feels so good to have the heat on your face. I love to take naps with the sun shining through the window in winter and on the beach in the summer! So, I guess, that's my kinda off track answer.
