The fortunate truth is that students in the UK are a low risk group for suicide
Yes indeed - thanks for reminding us, GetaHaircut The Guardian article inked to above actually states that : "Students have a lower suicide rate than the general population"
As I've already said, the kneejerk reactions in this thread that the reasons were "rubbish pastoral care" etc, don't really account for the complexity of these sorts of situations. As a tutor, I deal each year with troubled undergrads (and PhD students for that matter). We have some clear guidelines, but often these are met with resistance, or it takes a lot of careful persistent staff action to help students to see that they need to take some sort of action for their MH - of course, the inability to take action to look after themselves is a symptom of their ill-health in the first place, so it's tricky.
But I still remember from about 8 years ago, a student who was very troubled, and as we talked over several months in their first year (conversations that started because there were disciplinary issues around attendance & disrupting group work), they disclosed little bits of their life. It took time & persistence, but we were able to persuade the student to take a year of absence, to do something different, earn money & get away from some difficult family dynamics (financial dependence & its consequences was part of the problem). They were very resistant at first, but were just not participating & were set to fail. And their behaviour was jeopardising other students' work . By intercalating, they cleaned the slate, and when they graduated, my colleagues & I received a heartfelt card thanking us for persisting. They realised after some time away just how much they needed a break. And the student was able to find a way to deal with the family dynamics as well. A success story. But frankly - not one we could have managed if the parents had been involved - the student needed to make independent decisions.
