I have had a lot of trouble sleeping recently. I am constantly tired throughout the day but when I go to bed at night I can’t fall asleep. Instead I stay awake, memorising words to songs, timetables, etc. I have to get up fairly early to go to school, but often I can barely get out of bed, I am so tired. I do not drink much coffee or coke, and never after around lunchtime anyway. I’ve tried everything to get to sleep, but nothing works. Do you have any idea what my problem is and how to solve it?
