The last couple of days she's been noticeably better personality-wise (likely as a result of increased nutrition levels), but it's a very "up and down" kind of illness, it does mean that she's still in there and not totally swallowed up into the beast.
I'm fundamentally optimistic, and more optimistic now than I was a week ago.
The way the hospital gets past the 'not wanting to eat' is they give her a nose-feeding tube, through which they syringe a nutrition liquid. This is their base for getting them to non-starvation mode. My daughter had been eating enough to have tube removed a couple of days ago.
Having said that, it's a 12-month-ish program, and potentially a lifelong 'back of your mind' concern.
Starvation hampers therapy, but without therapy the individual wants to starve.
I know words don't help much, but I sincerely hope her situation improves.
