[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 ups and downs 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 secrets with you

You took all my secrets with you, oh

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
