Problem: 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?
