“I can't live a lie, running for my life”

Miley Cyrus – Wrecking Ball Lyrics on LyricsMode
EXPLANATION
She's saying she's being who she is, and who she wants to he. She can't be a fake little disney girl for her whole life.
EXPLANATION
She is still trying to find herself. She is running for her life, but she is also looking for her life. She doesn't want to be a fake, she doesn't want to be the girl everyone wants who he wants. She needs to be herself.
