Being SAD

It's four thirty in the afternoon, it's pitch black outside and I may be suffering the effects of SAD. Seasonal Affective Disorder. The now seemingly medically recognised type of depression which descends on many people at the beginning, and continuation, of the winter months. This condition makes you depressed, uncomfortable, negative, full of guilt, tension, despair and just generally low. In fact, very much how you feel after watching an episode of Eastenders. In other words, you quite simply cannae be ar*ed. According to the doctors it's all due to the fact we don't get much sunlight in the winter months. This would presumably be why Scottish people are well known for being consistently miserable - a theory, I hasten to add, that I don't always agree with. Apparently there is now also a Summer version of SAD which is called Reverse Seasonal Affective Disorder. A version where you presumably walk around ecstatically happy or still morose and depressed, walk around backwards, beeping repeatedly.
Of course, all this depression could just be down to the fact I'm trying to cover for my Line Manager, while he is off being a Dad to a newborn. Taking grief from aggrieved sales folk seems to sum up the job, certainly in the latter half of the week. The Doomhamers are a particularly grumpy lot and I've no idea why. I would perhaps put that all down to SAD as well if it was not for the fact they speak to us in the same 'off the sole of their shoe' manner all year round.
Since writing the past two paragraphs I've now been to the gym and feel great again. So I don't have SAD. Or at least, if I do I've found an easy enough cure. Doctors everywhere should take note. It's nothing to do with fancy light bulbs or happy drugs. All you need if you suspect yourself of suffering Seasonal Affective Disorder is a good kick up the jacksy.
