Demi Lovato has BP, and some of her songs, particularly "Skyscraper" and "Warrior", have helped me a lot. And Sara Bareilles has a song called "Hercules" which is about depression. Sara is my favourite artist, so I love everything she has ever released, but that one has been an inspiration to me during difficult times. "Chasing the Sun" is another one.
But based on the songs you have listed, I think we might have very different musical preferences.
