I am so sorry that all these young people are in this position. Please reassure your daughter that it is not unkind to feel out of her depth and to want to just have a normal uni start. From a safeguarding point of view, even though they are all over 18, I would make this something each parent deals with, just the same as you would if it was an acquaintance from school. If they had come home from school and said a child was threatening suicide, you would phone school, and their safeguarding team would contact parents and mental health services or emergency services if necessary. So at Uni, I would contact uni and keep checking with my daughter what was happening. It sounds like you're doing that but the major thing I am trying to get across I'd that you make it no responsibility of the young people. Their only responsibility is to be pleasant, invite this person to activities and inform welfare each time this person has harmed themselves or mentions suicide. I would tell welfare that it is not appropriate to get flatmates to watch or suggest solutions to the person. If this flatmate continues with self harm and suicidal talk, they must arrange for someone else to be responsible - either her returning home, or to accommodation with professional care if available If this person did commit suicide, imagine the guilt they may feel and the subsequent lives ruined if they felt they hadn't 'done enough'. I know someone who survived a serious suicide attempt and I asked what would have changed their mind. They said at the point of the overdose, absolutely nothing. I am upset for the person but the thought of 18yr olds trying to deal with this makes my heart ache.
