Lyric discussion by Femmergent 

This sounds like a song about self destruction. It compares the girl in her current state to the way she was when she was younger, and alludes to her sabotaging herself. The lyrics seem to hint that she had some traumatic memories and experiences ("I’m not afraid of the ghosts in your head/They won't torture you anymore"), and that she represses them ("I'm biding my time like she's biting her tongue/But I'm eating my words and reminding her"). The "bitter white pills" part also sounds like she might have a problem with drugs or self-medication. The narrator sounds like they're reminding her that she had potential in earlier years, and that she can find it again if she has hope.

@Femmergent the music video hints to the same kind of themes too
