S.A.D. (Seasonal Affective Disorder)

It's an interesting topic. I don't know enough of it to tell why, but I do know I always feel 'strange' during this time of year.
Here in the Netherlands the amount of sun-hours does not seem as low as in Scaninavian countries ... but while the sun is up (higher than the horizon) there are many days we do not see it! It's hidden behind a blanket of grey clouds (often with rain). Especially November and December are 'grey' months.

So, not only don't we get much sunlight, we (the Dutch people in general) also prefer to stay indoors because outside it's wet and stormy! I do my best to be outdoors at least for a little time each day (f.e. in the garden). I know I feel worse when I don't go outdoors for a whole day.
