I think that Rosy was trying to focus on what people can do to survive the PhD in good form, with recognition that anyone is prone to having a bad time with this, given the stressors and working conditions presented. I think her idea of finding out how people DO cope is important. I have full sympathy and empathy for anyone who is struggling with anxiety, depression and the like in the midst of their PhD. The PhD really invites this kind of response--so understanding how people are working to cope and stay well is important!
