Just wondering if you live within driving distance of a large city. There are more and more therapists who are trained to treat DID but you have to call them to find out. I have DID also and difficulty functioning with the anxiety. But, luckily there are a couple of dozen T's an hour away from me. The younger ones are most likely to be up on the humane, compassionate techniques.
I first had to face it that I must be helpful and accepting of my alters, and I had to know the T would have that compassion, too or the alters wouldn't even show up for therapy. It helps so much to have a therapist who never rushes you, who can support you and help with your feelings directly, in person. The purpose of therapy is to help cooperation so you feel better and have more free time. If anyone says it's to get rid of the alters, it just feels like a death sentence to them and they will get into a panic or rage.
