Hi Lisa, welcome to psych central. I'm sorry the women were triggered in your meeting. Thankfully people with DID are not monsters or crazy. Unfortunately, like anyone who has triggers or any type of PTSD, past abuse, etc, people with DID do struggle when something comes up that triggers something from their past.
For the most part, I would say that a person with DID needs most to have people around him or her to support and encourage. If these women are not capable of that, then I know for me, I'd rather not be in that situation. If these women were angry, it sounds like they have their own issues to deal with. I'd definitely talk to your T and/or read up on stuff.
Best of luck dealing with your group. I hope it will work out well for you.
