Something wrong.

There is something wrong with my health. Today I went to work as usual, but after sitting on the chair to sigh students’ communication books for a while, I felt sleepy! Then, I could not concentrate on what I was doing. And these days, I did not have the nice sleep condition in the middle of night. So now I decided to go to the doctor. Maybe I was too tired recently, and maybe I felt stressed because mid-term is coming. I do not know why, I just hope that I could recover as soon as possible. Because mid-term is around the corner, and I want to stay health to prepare it!
