This is not scientific but it is my best guess of the symptoms I experience at different times in my recovery.

Low Cortisol - inflammation & muscle pain of unknown origin, a deep and "crushing" sense of depression.

Low Thyroid - zero libido, tingling in limbs, sleep onset insomnia (due to high adrenaline levels the body raises tocompensate), oversensitivity to noise and light, heat and cold intolerance, melancholy depression, "dragging" sense of low energy


A very eye opening book about thyroid, for me, was "Thyroid Mind Power" by Dr. Shames. It has some fluff and supplement pitches in there, but also a really good overview of low thyroid symptoms and natural + prescription treatments.
