Lyric discussion by emukatze 

It's definitely about a girl who's driving away from an abortion clinic without having had the abortion. She's just driving without really knowing where she's going at this point and thinking about the baby.

I think the girl's family or friends (or perhaps boyfriend) want her to go through with it, since she fears if she goes back: "they'll take you in their arms and then take out their knives"

But she got to the abortion clinic and the "nice Christian lady" took away her resolve, plus she never really wanted to do it in the first place because of the guilt: "couldn't stand the thought of ghosts with a negative age"

"and you're thinking about how someone died that day the you that was so carefully planned but then again maybe this life is like a sleeping mountain waking up to shape the land" These lines reinforce that it was an unplanned pregnancy, but from the last two lines it seems that she has decided to keep the baby. I think the end of the song is a little ambiguous, so you can really interpret it either way, but mainly based on the tone of the song I don't think she decided to go through with it after all.
