I remembered it after a while, and I couldn't find it on Spotify.  I managed to find it again on youtube (I'm sure it disappeared), and it still makes me cry.  Some of the lyrics:

Break down, tears fall to the ground.  Tell myself, "There ain't nothing can't be found" when you're a fighter, you're a fighter you're a fighter, fight on baby

Some days I'm sure I've lost to fate, some days I cannot find my faith. But I just fight on, I just fight on I just fight on baby, baby

And I am a wounded warrior, and now that the enemy is closing in, I am a wounded warrior, looking for someone to let me in

Black and blue, I'm begging you take me in. I'm surrendering. Black and blue, but if I'm with you, If I'm with you, I'll live to fight on through.
