LamentEntertainment - I don't know if you are familiar with the novelist Terry Pratchett, but he had some youth-focused novels attached to his Discworld series of books focused on a young witch coming into her own named "Tiffany Aching". I didn't read them initially but, since the author is dead and won't be writing anything else, I decided to read those as well.
In one of the final two (read them both in the same week and things are getting muddled), he has a minor character named Amber that got pregnant, then got brutally beaten by her dad, and her baby killed, because he didn't approve. When she and her injuries were described, I pictured her as your Amber. She was in a serious dissociative state because of the trauma.
Not exactly the same thing as having your soul separated from your body, but I saw similarities, nonetheless. Made me wonder if you were aware of the series or not. If so, nice potential homage to the author; if not, it's an interesting and fairly easy read if you need something to do that isn't your job or this.
