WTF is up with my mind ?!?

I go to bed about 10:30pm, I'm not tiered so I stay up till like 2 ish, I'm a bit tiered, take 3 pills go to sleep, wake up at 7am and I'm Megga sleepy! Seriously, last week went to bed at 10, 3 pills, sleepy, got up at 6:am for school, fell back asleep and woke up at 1:45pm! Good thing is I got to skip school without my mum knowing, but what is up with my head :( x
