Just my thoughts.. To me it looks like in the first two stanzas her dad possibly or some father figure is ill and doesn't have long. Also within the second and third stanza she's saying that she's known all her life that eventually this moment would come. By the fourth stanza, this father figure has died and she's left wondering what most wonder which is why so soon? The part about not needing faith and truth to me is her saying she doesn't want to hear that God has him now and that his pain is over because he's in a better place. She just wants him back. But she does understand that no one ever leaves you because there were too many memories for to lose them.
