Why do i feel this way in the morning?

Almost every day I wake up in the morning and literally cannot actually "wake up" so to speak.. every muscle in my body hurts and i can't even open my eyes because my eyelids even hurt. I just feel so sore and immovable. when i wake up i have to lay in bed for like over half an hour to get enough strength to get out of bed. What could be causing this? I get plenty of sleep. I am an 18 yr old female. I drink regularly. I do exercise sometimes but that doesn't have any effect. Do any of these things play a part? What can I do to stop this? Ugh!
