Hey MFA, as far as triggers, i dont know what you can take and cant take and i dont really have any advice about how to lessen its impact, i still dont know myself.....As far as to wether you are a good nurse and no nice nices coming from me( i think you know that)......they are responding to your compassion and concern. You know whats its like, you dont feel uncomfortable with them, you understand, people sense that. Many psychologists and psychatrists and therapists enter the field in part because they have problems that they need to work out. I have the feeling that the opposite is true and that you are a very good nurse. When i was working, and had a life, during scenes of devastation, people, victims tended to talk to me about what to do, even if i was with 6 other people . I dont know how but subconsciously they pick up signals that you are approachable, and maybe understand something of devastation.
