The college is also acting In Loco Parentis, you should have been notified a long time a go.
Privacy laws re med treatment, school etc. have fouled such issues all up in many ways.
We were notified as soon as they realized it was a likelihood. Consider: If colleges called the parents of every kid (boy or girl) who was stressed, not eating right (neither enough, or too much!), not sleeping right...during Finals Week (which this just was)...then followed the advice of many here--Yank the kid out of school--I think the campuses of America might empty out tomorrow.
On the other hand, you're absolutely right. But we are convinced that those in charge at her school are on the ball. Merry Christmas.
