[Verse 1]
My voice got quiet, my smile got small
Been drinking more than I ever have, and I don't stand as tall
Catch myself lying when my mom calls
I find myself saying, "I'm fine", when I'm not doing good at all

[Pre-Chorus]
I don't recognize me now
I want myself back, give me myself back

[Chorus]
What was it about you
That changed everything 'bout me?
Don't laugh the way I used to
I'm saying things I don't mean
Nothing's ever gonna be the same
You didn't just break my heart, you changed my DNA

[Verse 2]
I don't get dressed now, I ignore my friends
And, it's not my thing, spending twenty-four hours in bed
I got empty pictures on all the walls
Been sleeping with lights on, it's too hard to get up and turn them off

[Pre-Chorus]
I don't recognize me now
I want myself back, give me myself back
[Chorus]
What was it about you
That changed everything 'bout me?
Don't laugh the way I used to
I'm saying things I don't mean
Nothing's ever gonna be the same
You didn't just break my heart, you changed my DNA

[Bridge]
Can everyone tell I'm somebody else?
Well, look at me now

[Outro]
Nothing's ever gonna be the same
'Cause there's all these parts of me you took away
You didn't just break my heart, you changed my DNA
