Be fine

"If it's a broken part, replace it
But, if it's a broken arm then brace it
If it's a broken heart then face it

And hold your own
Know your name
And go your own way (2x)

And everything will be fine
Everything will be fine"

(Jason Mraz-Details in The Fabric)

I don't know which one is broken, I just feel something going wrong.
Now I try to brace it, face it, .. and heal it. Yet what is 'it'?
