I'm Not A Girl Anymore

I'm not the girl you knew
I'm happier
And you can't break me
I found myself
And I don't need you
I'm cutting you out of my life
I don't wanna stick around you
Baby, you're toxic to my well being
You're like a cigarette
(So addictive, yet toxic)
I don't wanna play those games anymore
I'm not a girl anymore
