Lack of Sun and Feeling SAD

I am being to think that I might suffer from SAD (Seasonal Affective Disorder) because the last few days I have felt very run down and depressed with little energy to do anything. The constant rain means that even with the lights on in the house it still seems dark and dingy. Its easy to take the sunlight for granted but when you don’t see any for a couple of days its amazing the negative effect it can have on your mood. Its also been too wet to go running which puts me in a bad mood. Its days like this you just want to eat a big bar of chocolate, bring on the sunshine.
