Two songs have come to me in my life.
This one came when I was 15 and feeling very afraid a lot of the time. (I had been robbed at knife-point at my local regional rail station down the block from my house.) This song helped me be less afraid.
Do you know how strong you are?
Do you know how beautiful you are?
That you shine like a star in the night?
That you blaze with your own light?

The other came the fall both of my maternal grandparents died. We sang it at their memorial services.
Bury my heart but not my love;
carry that with you wherever you go.
We bury your heart but not your love;
we carry that with us wherever we go.
