Have you tried having your pituitary hormones checked?
Damage to the pituitary gland is a common source of chronic fatigue following TBI.
I found a good article discussion this and other subjects.

Quote from article: "
In the late 1990’s, Dr. Daniel Kelly observed in several patients the classic signs of pituitary failure; depression, fatigue and poor concentration (Lieberman et al. 2753)."
Maybe its worth a shot.
