I used to live in a darkened room

Had a face of stone

And a heart of gloom.

Lost my hope, I was so far gone

Cryin' all my tears

With the curtains drawn.

I didn't know until my soul broke free

I've got these angels watching over me.

Oh watch me go

I'm a happy girl

Everybody knows

That the sweetest thing you'll ever see

In the whole wide world

Is a happy girl.

I used to hide in a party crowd

Bottled up inside

Feeling so left out.

Standing in a corner wearing concrete shoes

With my frozen smile

And my lighted fuse.

Now every time I start to feel like that

I roll my heart out like a welcome mat.

Oh watch me go

I'm a happy girl

Everybody knows

That the sweetest thing you'll ever see

In the whole wide world

Is a happy girl.

Laugh when I feel like it

Cry when I feel like it

That's just how my life is

That's how it goes.

Oh watch me go

I'm a happy girl

And I've come to know

That the world won't change

Just 'cause I complain

Let the axis twirl

I'm a happy girl.

Oh watch me go

I'm a happy girl

Everybody knows

That the sweetest thing you'll ever see

In the whole wide world

Is a happy girl.

Oh, yeah...

Oh, yeah...

I'm a happy girl.
