I'll just mention my 2 bouts of depression in my life, a long one starting in 1991, after menopause, it went on for 10 long years....I felt it was sluggish thyroid but the doc never thought so with his "normal labs"...then my osteopath called in for desiccated thyroid in 2002, and the long depression lifted in 4 days. It was thyroid all those years.

Then another bout of lowness, hit me in 2006, and it was Vit D deficiency.

I don't know about the meds you take or about the concusson and depression.

And for me, grape seed extract which I'm headed into 20 yrs, has been a goodsend in my life...never had the brain fog issue I hear so much about from others who claim the Fibro issue. I've posted about OPC's (grape seed ex) many times here, and on the vits/supps section.
