I'm so sorry to hear this. It just sounds outright unfair in every way. And as much as I'm realistic about the world, I hate when justice isn't served.
I know it's very easy to gush about your own child but she is such a hard worker. She has a chronic illness, a master's degree and is currently studying for another part time (on a full scholarship!) and hasn't taken a single day of sickness/leave off for either in months. And she's passing with flying colours!!! She'll take a lot of slack but being called lazy/not hard working/etc seems to really hit her right in the heart.
I wish she saw herself as I (and I'm sure her friends) see her
