if its the wrong diagnosis you get the wrong treatment plan and confidentiality laws are there so that no one OUTSIDE your treatment team knows your diagnosis unless you give permission for them to know or tell them yourself. A professional (primary physician, psychiatrist, psychologist, therapist...) needs access to your past record so that they know what works for you, allergies and so on. Sometimes in the diagnosing process the person recieves many different diagnoses based on professiona knowleg=dge at the time, and how and what symptoms the client hides and discloses. This causes treatment problems and undue stress on the client who is trying to obtain the correct treatment plans. So I prefer the profession see me first as a person and then deal with the diagnosis after. So I tend to HATE diagnosis labels.
