You are doing an incredible job considering how young you are, NH.
The fear is really chemically-driven. There’s not much you can do about it right now, but do everything to comfort yourself, and keep telling yourself over and over that people who know about this syndrome say you are healing even as we speak. You will feel better. You will recover.
