maybe you should point her towards one of the savings type websites, I know I've read alot of suggestions on them on how to save alot of money on healthy foods.

Or gift her a book, like healing with wholefoods or something like that.

She could ask the doc about deficiencies with her daughter. Maybe if she's on a tight budget, she is taking her daughter to whatever bulk billing doc is available (as I have done in the past), and they (in my experience) might not have the time to do anything but hand over a script for the current illness so they might not look at that side of things, but it is a possibility.

the syptoms you described could be a deficiency of b and c, or not

I think most illnesses should be looked at from a preventative pov, and a healthy diet couldn't hurt.

She could at least try a good multi vit and see if that helped.
