Does anyone else go through times where they just can barely stay awake all day? I'm completely worn out because I have to wake up around 5:40 - 6:00 AM for school. I go to sleep at like, 9:00 - 10:00 PM, so it's not like I go to sleep really late. Even when I do get a lot of sleep, I'm still very exhausted when I wake up. It's not normal because you know, I sleep to feel less exhausted, not more exhausted. Do you go through this too? I'm constantly exhausted and I don't know why.
