Okay, so last night I go to bed at 10:30, I wake up at 7:30, so that's 9 hours of sleep, and all day today I'm still tired. I've heard of being tired from too much sleep, but then some nights I'll go to bed at 12:30 and wake up at 7:30, for 7 hours sleep. Or even go to bed at 11:30 and wake up at 7:30 for 8 hours sleep. What is it? I'm always tired. I'm falling asleep in the mornings at school, then wanting to pass out while I work in the afternoons. I just hate being so tired all the time.
