For anyone that finds themselves in that sort of situation, you may be able to find some counselling if you're willing to ask for it. I know our local Red Cross has a team of volunteers (Disaster Mental Health) that can do critical incident stress debriefing (CISD). If someone called up the chapter and talked to the disaster department, they could probably hook them up with a counselor. I don't think our local CERT teams are far enough along to have that available, but they might be able to access fire/rescue resources since they're affiliated with them. A lot of churches could probably refer you to someone good or may even have someone on staff.
