Horrible. Goes to show how seriously nurses take their jobs, and when there's an error how devastating it can be. She is not the first, nor I'm sure the last, to take her own life after an event/error. Hospitals absolutely need to provide support to nurses after events like this.
One correction though, it was my understanding that Jacintha was not the nurse caring for Kate. Rather, the nurse who transferred the call to Kate's nurse:
"The mum-of-two had been duped into putting through a hoax call to Kate’s nurse from Aussie DJs pretending to be the Queen and Prince Charles.
Devoted Jacintha was on reception when she took the call from 2Day FM pranksters Mel Greig and Michael Christian and transferred them to another nurse who gave out sensitive information about sick Kate."

I don't know why, but this makes it even more sad to me. She wasn't even the one who divulged information over the phone, and yet she still took her own life. Really highlights how something like this can be devastating to a nurse, not just professionally, but personally as well.
