I have severe fatigue, no motivation, no energy. i sleep fine and really have no stress. i have seen therapists and family doctors.

If doctors have not: found a medical explanation and therapy has not been helpful, and if you have not yet had a psychiatric evaluation, then consider one. There are many possible explanations but must consider if depression and/or chronic fatigue syndrome (CFS), a debilitating and complex disorder characterized by profound fatigue, may be producing your symptoms. Best regards for relief.
