what is it?

6.00pm : i watched the movie, but i don't follow the story

8.00pm : i read the jokes, but didn't know when to laugh

10.00pm : i play badminton, i lost it all..

1.00 am : i lay on my bed, but i don't sleep.

5.15 am : woke up, feel the same...

8.00 am : i write on the blog, but every words is flat

i can't depend on my eyes when my mind is out of focus

what has gone wrong with me, maybe i know..but....
