Found this in the telegraph (sssh I don't usually read it but google took me to it) and thought this might be relevant to the discussion:
The issue of student suicides has been highlighted by a spate of recent deaths in Edinburgh, where seven students have taken their own lives. Among them were Catriona MacAulay, 18, a first-year psychology student at Edinburgh University, who hanged herself in May in the stairwell outside her city centre flat, shortly before she was due to sit her exams. Another victim was Kate Hodgson, a first-year medical student, who died after a fall in November, having previously told friends that she did not like her course and was finding it difficult to cope.
A study at Edinburgh University, prompted by the tragedies, concluded that while the number of suicides was "unacceptably high" there was nothing to suggest that students in the city were more likely than other young people to take their own lives.
Oxford University, which suffered a spate of student suicides in the early Nineties, reached a similar conclusion in 1997, despite being blamed by the family of a 22-year-old student, Sarah Napuk, for her suicide shortly before her final exams that year. It said that suicides, some of which were "unpreventable", were not especially high among students.
The National Union of Students has also warned that student suicides are on the increase. Its research showed that 61 per cent of undergraduates suffered from depression during their first year, with 12 per cent reporting that they felt suicidal at some point during their studies. One cause was the breakdown of parents' marriages, which often occurred soon after students left home to begin their university course. This led to a "January phenomenon" in which undergraduates returned to college after the Christmas vacation suffering from depression caused by the impact of parents' separation.
