I have been incredibly sleepy these days. Yesterday I couldn't wake up when I had to. The bell rang and I stopped it,then I slept again soon. I realized that I overslept when I woke up next time. I was really shocked. I have never done that kind of thing recently. I can get up even after only three-hour-sleep most of the time. Why am I so sleepy? I think that I am very tired mentally. Because I am worried about my son and I have the fear of becoming unemployed. On the other hand, I also know I shouldn't be scared too much about my future.
