Anybody knows the title of this song..?

sometimes i get angry and dont know how to show it sometimes i think very bad thoughts about you
i secretly love you and i dont think you know it
someday i will grow out of this i cant wait until iam rich and far away....
dont know if i got the lyrics right but anyway, if anybody knows the song please let me know.... thanks
