I think the song you are looking for is called Let It Go

The Lyrics are:
I’ve been caught sideways out here on the crossroads
Trying to buy back the pieces I lost of my soul
It’s hard when the devil won’t get off your back
It’s like carrying around the past in a hundred pound sack

{Chorus}
Today I’m gonna keep on walking
I’m gonna hold my head up high
I’m gonna leave it all behind
Today I’m gonna stand out in the rain
Let it wash it all away Yeah wash it all away
I’m gonna let it go Oh yeah
I’m gonna let it go Oh yeah

Skeletons and Ghosts are hiding in the shadows
Threatening me with all the things that they know
Choices and mistakes, they all know my name
But I’m through holding in and holding onto all that pain

Today I’m gonna keep on walking
I’m gonna hold my head up high
Got No more tears to cry
Today I’m gonna stand out in the rain
Let it wash it all away Yeah wash it all away
I’m gonna let it go Oh yeah
I’m gonna let it go Oh yeah

I know I know I know I’ve been forgiven
I know I know I know I’m gonna start living
Today I’m gonna keep on walking
I’m gonna hold my head up high
I’m gonna leave it all behind
Today I’m gonna stand out in the rain
Let it wash it all away Yeah wash it all away
I’m gonna let it go Oh yeah
I’m gonna let it go Oh yeah
Oh yeah
