Last week, my tummy felt bloated. I don’t know why it happened. Is it a natural event? The day before I got sick, I immediately felt sleepy. I think it’s because I only got six hours of sleep, and my body needed enough rest. The next morning, I started to feel something bad. It seems like I need to release all the fluids all over my system. I had just drunk coffee then, yet I slept immediately. It was also why I didn’t go on the first day of class, although I finally recovered.
