  (E)              (F7)
Oh sweet lungs don't fail me now
     (F#7)                  (E)
Your burning has turned into fear
                   (F7)
It drills me in my every step, Im moving quick

(C#)
Just one more breath, I beg you please

My body needs a reason to cross the line

Will you carry me there one more time

[Bridge]

(D)              (B)
I have reason to believe
            (Asus2)
That I have victories to taste
(D)              (B)
I can feel them on my teeth
        (Asus2)
Upon my lips

And in my chest
(D)   (Ebar)  (Bbar)  (A)
I can roll them on my tongue
(D)   (Ebar)  (Bbar)  (A)
They are more supple than defeat
(D)   (Ebar)  (Bbar)  (A)
I feel the tension in my lungs
(D)   (Ebar)  (Bbar)  (A)
And every move is filled by my resolve to
