It could be a flare up of chronic fatique syndrome or fibromyalgia, since all your blood work came ok. I have both cfs and fm, I have days and weeks I stay in bed due to the exhaustion, then depression due to the body not felling well. But doing better with the depression, because of understanding the cfs and fm. I always feel worse in the fall, when we have the cold fronts coming through, and stress makes me feel bad too. Our symptms sound alike, but the symptons are common for other things. Please email if you like and God Bless.
