[Verse 1]
You knew which parts of my body I was insecure about
You knew what I thought about all my friends when they weren't around
You knew which days I was prayin', and the days that I wasn't
I told you everything

[Chorus]
'Cause you were my human diary
So when you left, you didn't just leave
No, you took all my secrets with you
You took all my secrets with you
And now you're with someone else
And thinkin' 'bout it hurts like hell
And you got all my secrets with you
You took all my secrets with you

[Verse 2]
You knew how to make me weak in a good way and in a bad
You knew the up's and down's in my relationship with my dad
Oh, and damn, how I hate it, that you know me naked
I gave you everything

[Chorus]
'Cause you were my human diary
So when you left, you didn't just leave
No, you took all my secrets with you
You took all my secrets with you
And now you're with someone else
And thinkin' 'bout it hurts like hell
'Cause you got all my secrets with you
You took all my secrets with you
[Bridge]
Now you've got a piece of the sacred parts of me, oh
Now all my secrets are in another girl's bed

[Chorus]
You were my human diary
So when you left, you didn't just leave
No, you took all my my secrets with you
You took all my secrets with you
Whoa, whoa, whoa
Yeah, you took all my secrets with you
You took all my secrets with you, oh

[Outro]
Yeah, you took all my secrets with you
You took all my secrets with you
