Some of these symptoms could be adrenal? That also may explain why you feel worse at different times of the day - i.e. your cortisol levels may be normal in the evening but low in the morning. From memory I think a normal cortisol pattern is high in the morning (to give you energy to get up and get going) and it drops off at night so that you sleep. If you had low levels in the morning then you would feel tired, but your levels may be normal or even too high at other times of the day. Just a thought. . .
