Tired all the time but can't sleep?

Basically, I workout vigorously every day, eat relatively healthy and don't smoke or do drugs, but I'm constantly half asleep. I feel like a walking zombie and it takes an insane amount of my will power even to get up out of bed or go to the gym. I thought that if I just kept going eventually I would ease into it but I haven't. And i find it incredibly difficult to get to sleep, next to impossible. I probably sleep around 6 hours a night if not less most nights because I can't fall asleep and then I feel like I'm dying all day. Is this just chronic insomnia? What would cause this?

Also, is this really bad for me? Like life threatening bad?
