One of many rescuers

I've heard this script before
I know this turn of mind
You think that you're the one
to bring the change she's trying to find
But what you're selling she don't need
she already got it free
Your boat struck something deep
now you're trying to save the sea

You ain't Sir Galahad - she ain't your blushing bride
You ain't the wayward son come back to turn the tide
You ain't the saviour king foretold and prophecied
You're just one of many rescuers trying to get by her side

She put her hand around the flame
more times than you can tell
The best thing you can do for her
is to pass and wish her well
She ain't dying on her feet
or hanging on your every word
The pain you're sensing is inside you
