Very hard to choose one but i have Eminem's Beautiful Pain on repeat right now. ..its about overcoming adversity, burning the past and starting fresh. Here are some of the lyrics:

'Yesterday was the tornado warning, today is like the morning after
Your world is torn in half, you wake and let's wait to start the morning process
Rebuilding and you're still a work in progress
Today is a whole new chapter, it's like an enormous *****
The thunderstorm has passed ya
Your weather didn't poke his eyes out with the thorn bush that you
Used to smell the roses, stopped to inhale can't even tell your nose is stuffed
So focused on the brightside, then you floor the gas pedal
And hit the corner fast, the more asserted
Never looking back, may hit the curb
But everyday is a new learning curve, as you, steer through life
Sometimes you might not wanna swerve
But you have to to avert a disaster, lucky, no permanent damage
Cause they hurt you so bad, it's like they murdered your *****
And threw dirt on your casket, but you returned from the ashes
And that hurt that you have, you just converted to gasoline
And while you're burning the past, standing at inferno and chant

I'm standing in the flames
It’s a beautiful kind of pain
Setting fire to yesterday
Find the light, find the light, find the light'
'
