I previously worked with a woman who has DID. She has allowed me to share information about her case for educational purposes. She had a severe history of sexual abuse dating back to when she was 2 until 14. There was additional abuse after that age.You will see that the handwriting and language changes with her personality. Here is some interesting evidence that you might get as a clinician.I look forward to doing so once you answer this question. I encourage you to really be specific when it comes to this question. It is very true that some clinicians and doctors do not believe in DID. I would also love to hear your opinion. Why does this disorder develop if you believe that it exists?
