Love this! :3

Good writing I suppose. Not terrible, not exceptional. Good.

As for characterization... No 15 year old sounds like that. I don't care if they have a genius level IQ, they don't speak like that. I consider myself mature and I don't speak like that. Were I you, I would have made her older, at the very least in her late teens.

As for the "God will steer you in the right direction" part, again, it goes back to her being 15. This is terrible advice to give your 15 year old, with that advice they're going to go out and pork the first boy they come across because at 15 *everyone* is a hormonal mess and most people think they love their first real boyfriend.

Again, over all not exceptional, but not bad.
