One other suggestion I can come up with right away is to call
NAMI. They can sometimes help with other resources in a persons
area.
Also you can see if the doctor's would do a homebound program for
her. By putting her out of school for a short time. And having homework
sent home.
This might be a way to get the grades back up too.
The school could then do a 2 hour or 4 hour a week tutoring.
