As for me, the most tired thing is fastidium. Why? A friend said, the tired of hard-working, you can recover by rest; but the tired of fastidium, you never know how to cure it. Absolutely agree with her, these days I happen to catch with such emotion, which make me depressed a long time. Then it cause I don't have any interest on reading, listening, talking, sleeping, which make my life in a chaos, so bad, so bad,so bad!
What does I want to say, yeah, I want to caution against those friends in my situation, if you have job, pls try to enjoy your work, if you are still on study, pls be absorbed in your learning, or you will be boring just like me, it's a very painful experience for me, I hope you are never experience it.
