I have SAD so crappy weather always affects me but this year it has been so much worse. It really makes me wonder what a basket case I would have been if dday had happened in the winter instead of the beginning of summer. I honestly don't know if I would be here.
Vitamin D helps. I take mega doses and try to exercise and get out in any patch of sun that appears. But it is all I can do to keep from hiding under the covers until spring.
