"DNA" lyrics

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

I don't recognize me now
I want myself back
Gimme myself back
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

I don't get dressed now
I ignore my friends
And it's not my thing spending 24 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

I don't recognize me now
I want myself back
Gimme myself back
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

Can everyone tell
I'm somebody else?
Oh look at me now
Nothing's ever gonna be the same
Cuz there's all these parts of me you took away
You didn't just break my heart
You changed my DNA
