Im a high school student and I just cant sleep, its already 3:00 am here and I have to wake up at 5:00 am and be ready at 6:00 (my transportation to school is 40 mins - 1 hour) and my school time is 7:00 am-4:00/5:00 pm (depends on the schedule). How can I be energetic and not sleepy in school if I havent got much sleep?
