Sleepyhead

Sup guys. I’ve been thinking lately, why am I always sleepy in class. Every subject, every time I should say. Today, after recess, I and my classmates had to go to library. In library, while everyone is busy doing their work, reading their books, I fell asleep. I was reading my book, of course. And I started to felt sleepy. I put my head on the table. & guess what; I fell asleep for about, 20 minutes or something. I woke up and continue reading and then I fell asleep again. I swear to God that I was too drowsy till I can’t even open my eyes.

In Maths, the same thing happens. I slept early last night, why I still sleepy in class for this two days straight? Can someone help me? Is the subject too boring? I don’t think so. Asal bukak buku je, ngantuk. Tak tahan tak tahan.
