people on yahoo suggested that this is
Alissa Moreno - Wildfire
nevertheless, lyrics are only similar to yours
Everytime you think that you won’t make it
And each time you’re convinced that you can’t take it
Picture me in this light, think of me, you can fight
Cause I’ve been chewed up and spit
I’ve been big, I’ve been hit
I’ve been burned, but I have learned
That we survive, we get by
We take the hit and we learn to fight
We collide, but we don’t die
Trying to put out wildfires
