Hi Jodi..
welcome aboard

To find support groups on a specific disorder like Dissociative Identity Disorder contact your area's county mental health agency, psychiatrists, psychologists, and other therapy type agencies and area rape crisis and domestic violence agencies. They will be able to point you in the right direction for therapists that run mental health disorder type support and therapy type groups.

You will find my experience with DID and therapy for it in my blog here on this website. To get there click on "Blogs" at the top of the screen. That will get you to the blogs homepage. click on "users" or the words "get your own" then click on the word "memyselfandI" which is the name of my blog.
Take care in reading it though some of it has a bit of graphics.
