nothing is as simple as we hope it will be

I'm yawning and yawning. I have a bad habit, and it is staying up late at night when there is school the next day or a few hours later. I am trying my very best to stay awake for each lesson despite the fact that I'm really very very tired. What's up for tomorrow will be the English Debate! Am scared and am nervous, I'm suck at it! If I'm not wrong, I will be the first person who speak in front of 40 students, oh my gosh, I don't even want to think about it. Freak out!

I really have to thank Jiahching for the concern she has showed, I really appreciate it a lot. Thank you Jiahching ♥! Although you are a year younger than me, but you seems to know a lot to this kind of situation. You're right, I'm too emotional! I'll try to change if possible.
