so why does SAD seem to peak in February?
It might be that you "sense" spring but it's not really here...YET. The flower beds are starting to wake up, the birds that migrate are starting to be seen and so you might be getting the "feeling" of spring but not with the warmth.
I fight SAD "symptom like feelings" (I've never been diagnosed) for as long as I can remember. My mom on the other hand has been diagnosed and she uses the light therapy and it's been working. My "light" therapy is, when the sun is out, like today, I'll pull a chair close to the most brightest window. I fortunately have a sliding glass door where the sun shines directly in. And I just soak up the sun. I feel soooo much better after that. Can you do this?
Ever wonder why bird migrate and bears hibernate? They may be on the right idea... Maybe I'll join them next winter...smart critters
