Although it is important to be able to recognise and disclose symptom of physical illnesses or injury, you need to be more careful about revealing psychiatric symptoms. Unless you know that your doctor understands trauma symptoms, including dissociation, you are wise not to reveal too much. Too many medical professionals, including psychiatrists, believe that hearing voices is a sign of schizophrenia, that mood swings mean bipolar disorder which has to be medicated, and that depression requires electro-convulsive therapy if medication does not relieve it sufficiently. The “medical model” simply does not work for dissociation, and many treatments can do more harm than good... You do not have to tell someone everything just because he is she is a doctor. However, if you have a therapist, even a psychiatrist, who does understand, you need to encourage your parts to be honest with that person. Then you can get appropriate help.
