I have also experienced hair loss (can't do anything about it), fatigue (as odd as it sounds, exercise gave me more energy), loss of libido, and weight gain (tracking calories along with exercise fixed that).
The fatigue and loss of interest in most things are also signs of depression, which you say you are experiencing--are you being treated for it? My husband started anti depressants a month ago and his transformation back to the man I married has been wonderful.
