Hi Lydia,
I'm so so sorry you're dealing with this. Are you sure your psychiatrist is really the only one who specializes in DID in your area? If you want PM me and I could try and look into that for you. Maybe there's someone else.
I'd love to see you get away from these people, especially the team leader! Is she a licensed psychologist or something? I think she should be reported eventually, though I know that would probably be too scary right now.
My only other thought is trying to find a therapist totally outside of this program or whatever this team is a part of, to give you a different perspective and someone who can totally support where you are right now which is coming out of being the victem. Maybe you and this other person could brainstorm about what to do with this awful group of people that call themselves helpers.
Let me know if I can do anything!
