Hmmmmm..........For some reason, even when I go to bed earlier than my friends or stay up as late as them, they seems more awake and energetic than I am. Moreover, my teachers' voices are super soothing. Such that I can fall as sleep so easy in their classes. During the last test for one of my class, I was so sleepy and tired that I couldn't focus on the problems. What do I do now???!! I really want to pay full attention in class and I tried super hard to (believe it or not); but I can't if I keep on sleeping T-T
