Emily First Girl does some wonderful work at her blog. I highly recommend it for anyone with a dissociative disorder and their significant others. She has posted a survey on her site for people with more than one diagnosis. She’s taken care to keep the survey anonymous, so survivors can feel comfortable responding. Follow this link to take her survey.
Looking forward to seeing the results, Emily.
Update: The first link I posted here went to a tag that would likely be deleted soon. If you clicked that link and couldn’t find the survey, please try again now. Emily sent me the link to her direct page, so it should be there. Sorry for the mix-up!
