Your friend’s daughter attends Tulane, and lives in the same dorm as someone who committed suicide? If this is true, there may be a crisis team at Tulane who is there to respond to students affected by such events.
At my daughter’s college, when she was a sophomore there was an attempted suicide in her dorm. After the student’s needs were addressed and the ambulance took him away to emergency medical services, there were counselors from the student counseling services who went door to door checking on the other students in the dorm and offering support to anyone who felt affected by the incident. They also provided information about resources in the event of a delayed reaction. As a mental health professional I was pretty impressed with this response.
