You Know Lyrics

Lyric discussion by coldblooded8murderteen 

I adore this song... I don't really understand what it's about, maybe because my english is not very good...

But here is how I imagine it: I think it's about someone who used to be very popular and had a good life, at least they thought it was, but now everyone realized the truth about this person and how empty she is. She realizes that it was all empty and doesn't know how to live and everything seems pointless, but at least she knows the truth...

But I don't really understand the lyrics. Anyone?
