Have you described them to your T. The ones you know anyways. I am new to the whole DID thing but as I learn of new Alters I will tell my T what I call them. Sometimes I don't even have a name for them I just describe an attitude or a personality that kind of takes over me. He always says that he's willing to talk to any of them when they're ready but he never pushes it. He just says in general that he's open to listening to whoever wants to talk but he would never pressure me. Maybe just give him a little bit of information about the ones you know maybe that will get him off your back. He also tells ask me if I know what a certain alter wants or needs sometimes they will tell me and I will relay it to him but other ones won't talk and I just tell him I don't know yet. I know he wants to know so that he can help us. One of my alters really had a dislike for my T and when I told him that the alter didn't like him because he was trying to make me better and get rid of him my T was able to clear things up and explain that he does not want to get rid of the alter. It's a mean alter and that really helped. Ever since my T said that I have not been getting the static and the constant cursing in sessions from the mean alter. He seems to understand that T doesn't want to get rid of him any longer and has calmed down quite a bit.
