I think I get what she's saying!
She's referring to her historic rise and being the "it girl" from 2009 to 2010, when she was pretty much at the top of her game.
But in 2012 to 2013 she kind of fell off the radar and declined drastically (musically and relevancy), leaving her to now feel what's it like to be at the bottom.
She's now reminiscing about how good it feels to have the public's adoration and to be in the spotlight once again. It's kind of sad when you think about it, almost like the ending to her SNL skit.
Anyways, hope I made things more clear.
