For what it’s worth: she has a meeting with her dean tomorrow (I also spoke to her dean, a very warm and helpful woman), had a meeting with the health center today, and is registering with disability services. All points to the likelihood that she will be granted a medical withdrawal from the class she is in danger of failing. She seems to be breathing a lot easier now.
We’ll be having some serious discussions over break, but for now we do not want to add to her considerable stress during finals.
I want to thank everyone who has commented here. It’s wonderful to have this support and sounding board, and some of the suggestions given her have been really helpful. Thank you!
