She says, "you don't want to get this way
Famous, and dumb at an early age"
Lying, I'm lying
Carmen has essentially sold her soul to become who she is now all in her teenage years.
Carmen is a parrallel version of Lana Del Rey, telling her 17-year-old self to get off the drugs and alcohol and make something out of her life, because this is how she would have ended up. I’m lying refers to the fact Carmen is bitter about not having changed like Lana did, and wanting Lana to be the same.
