It's a bit of a depressing song, but a song called "Reindeer King" by Tori Amos has helped me out a lot. I was recently diagnosed with prostate cancer and my world has turned upside down. I'm on androgen deprivation therapy and feel like I'm not myself. The lyrics of this song really speak to me. Some of them are:

Crystal core
Your mind has been divided from your soul
Now you say you are that stranger on your shore

Grief it brings the need, the naked freeze
Caught in the frost
Numb, unbearable thoughts, your inner need
Fire not lost, no way, not lost

You gotta get you back to you
Get you back to you

Crystal core
You are at the still point of the turning world
The divide
Fearing death, desiring life

You gotta get you back to you
Get you back to you
