Normal to be extremely exhausted?

Kate

Is it normal to be so exhausted and tired all the time? I sleep for like ten hours and have to force myself to even get out of bed and then when I finally do I can't barely move or keep my eyes open, I'm just SO tired and nothing helps. I'm not low on any vitamins so it worries me honestly that I just collapse on my bed or couch constantly because I physically can't do anything.
