hi freewill,
Our system had this happen a few months ago. when Little, our 6-year-old, remembered something that was said to us during our CSA and heard our current bf saying it, she took over, went hysterical, and told him he couldn't talk to anyone inside anymore. She wouldn't let anyone else take over either, 'to protect the bigs who like bf too much'.

I'm sorry you're triggered right now and I hope your system gets to feeling better soon. All I can say that helped in my case was for us bigs to let her write out what she was feeling in the journal and be 'big' and protective of us. In the end she calmed down, especially because everyone was taking part of the pain too (she had been shielded from everything before, we thought), and she was able to go back to being herself... loving puppies, singing, coloring again. I hope this helps in some way at all...
