Negative thinking

I don't know whats wrong today, actually I think I know...not get enough sleep...This is not my first time for staying up all night, I often do that if I read really good novel hehe...but I don't know this time suddenly all the negative thinking is just coming out of my mind...Oh, I have stop this....And reading about "the laskar pelangi story" from the internet is not make me feel any better. Why they have to do that? I mean why you can you just enjoy other people happy? Why do you have to ruin everything by saying bad things...I guessed that is the risk of being famous....
Maybe I should find happy reading, just to lighten my mind a bit.
