```

Let it go, let it go

Can't hold it back anymore

Let it go, let it go

Turn my back and slam the door

The snow blows white on the mountain tonight

Not a footprint to be seen

A kingdom of isolation and it looks like I'm the queen

The wind is howling like the swirling storm inside

Couldn't keep it in, Heaven knows I tried

Don't let them in, don't let them see

Be the good girl you always have to be

Conceal, don't feel

Don't let them know

Well, now they know

Let it go, let it go

Can't hold it back anymore

Let it go, let it go

Turn my back and slam the door

```
