At the end of the visit, when I asked him which symptom was most bothersome to him, he actually stated that his fatigue was most troublesome.  He did not even mention this on the initial part of my history taking.  When I asked him to describe this further, he states that he experiences a general exhaustion.  He basically lays in bed all day everyday.  I asked him if he was depressed, he states that he is treated for depression.  He is unsure if this is optimally treated.  As I just mentioned, he stays in bed almost all day long and does not engage in any social activities.  He does not think that he is necessarily sad.  His appetite is good.  He has never undergone any psychotherapy for depression.
