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
Crying 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 the happy girl, everybody knows
That the sweetest thing that you've ever seen
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 the 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 the happy girl, everybody knows
That the sweetest thing that you've ever seen
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 the happy girl and I've come to know
That the world won't change just 'cause I complain
Let the axis twirl, I'm the happy girl

Oh, watch me go
I'm the happy girl, everybody knows
That the sweetest thing that you've ever seen
In the whole wide world is a happy girl

Oh, yeah, yeah, yeah, yeah, yeah
I'm the happy girl
Oh, yeah, yeah, yeah, yeah, yeah
I'm the happy girl
