I would suggest that you make a detailed list of your symptoms and bring them to your psychiatrist. Perhaps he misunderstood you and this could explain why he did not provide you with a satisfactory response. It might have been a simple miscommunication. A detailed list would give him the opportunity to fully analyze your symptoms and come to a conclusion about what your diagnosis might be.
If you do try to speak to your psychiatrist and still feel as though he is not addressing your symptoms, you can always seek a second opinion or even a third. Search for a mental health professional who specializes in the treatment of dissociative identity disorder (DID) or who has experience treating individuals with this disorder.
Some clinicians never see a case of DID during their entire careers. This could explain why some mental health professionals are not fully convinced that DID exists, although it is a recognized disorder in the DSM-IV.
Though you might have DID, it’s also important to realize that you may not. It’s best not to assume that you have the disorder. At this time, I think it’s important that you are properly evaluated by a mental health professional. It is imperative that you do this sooner than later especially because of your fear that you may harm someone. It would also be helpful if you had a trusted friend or family member who could be with you and monitor your behavior. This person could objectively verify whether or not you are engaging in a particular type of behavior. He or she could also speak to your psychiatrist and corroborate your behavior and symptoms. This might help your doctor to understand more of what you’re going through.
I hope you’re able to find the help that you need. If you believe that you may be a danger to yourself or others, please do not hesitate to go to the emergency room for a psychiatric evaluation. The emergency room can provide you with immediate help. Please take care. I wish you well.
