Always fatigue/tired!!

[Pupil]

Could anyone give me any suggestions on how to overcome severe fatigueness? I am always tired. Overwhelming tired. I never have enough energy to do anything. I am always in the daze, unable to concentrate, and barely able to comprehend basic things. I've been like this for over five years.

I had a physical done and everything looked okay according to my physician. I jog at least three to four times a week. I try to eat as healthy as possible. I take vitamins daily. I try to sleep at least eight hours a night, but to no avail, I still wake up tired.

I am so tired of being tired and fatigue! It is ruining my life!!
