Complicated

Why i could not sleep? I tried to close my eye and ask my brian to shut down, but why i'm still a wake?
My feeling is so complicated, i don't know what i really want, what i should choose, which way i should walk through?
Why i can choose to apple and watermelon? Why the nature didnt have apple-watermelon together?
Why the popular book that i used to read don't have mini dictionery for me to find when i don't understand? Why i have to read this book? Why not let the book read me.
Why pp is so unfair? Why we could not be together?
Why you are so far? Why you are so foreigner? Why and why?
Anybody can give me the answer?
