About "She Used to Be Mine"

It's not simple to say
 That most days I don't recognize me
 That these shoes and this apron, that place and its patrons
 Have taken more than I gave them
 It's not easy to know
 I'm not anything like I used be, although it's true
 I was never attention's sweet center
 I still remember that girl
 She's imperfect, but she tries
 She is good, but she lies
 She is hard on herself
 She is broken and won't ask for help
 She is messy, but she's kind
 She is lonely most of the time
 She is all of this mixed up and baked in a beautiful pie
 She is gone, but she used to be mine
 erse 2]It's not what I asked for
 Sometimes life just slips in through a back door
 And carves out a person and makes you believe it's all true
 And now I've got you
 And you're not what I asked for
 If I'm honest, I know I would give it all back
 For a chance to start over and rewrite an ending or two
 For the girl that I knew
 Who'll be reckless, just enough
 Who'll get hurt, but who learns how to toughen up
 When she's bruised and gets used by a man who can't love
 And then she'll get stuck
 And be scared of the life that's inside her
 Growing stronger each day 'til it finally reminds her
 To fight just a little, to bring back the fire in her eyes
 That's been gone, but used to be mine
 Used to be mine
 She is messy, but she's kind
 She is lonely most of the time
 She is all of this mixed up and baked in a beautiful pie
 She is gone, but she used to be mine
