After several days of SI and threats that some could take over the appointment, we were able to calm down and talk to the new therapist about everything. Words came pouring out, some from me, some from others inside. We didn't say everything though, we take our time to trust

She says she thinks the dissociation is a serious concern, that the Bipolar dx is maybe too reductive given the context of my past, and that on the surface I don't seem to show signs of CPTSD, but regarding the latter we'll see with time.
We mentioned our multiplicity twice, without jumping into any specificities, and she was very respectful of our need to take our time.
The appointment was really long, I'm very tired.
