How does Mary call put others before herself (textual evidence)?

From the text:

"Lord, I've said it before and I'll say it again: You sure made some mistakes when You made me. Surely to my soul I must have moss growing on in my head where my brains should be. Nobody but a poor dement would do what I'm doing, hiding my old dead daddy over there on Old Joshua. Taking me on three snotnosed kids to raise. If I had the sense of a rabbit or even half that much I'd just take off across that bald over there and go down the other side of it and just keep right on walking and never look back. They'd make out all right without me. Probably even better."
