Yes it was very scary at first. We were in therapy for BPD and as 6 years passed in therapy and attempts at DBT failed my T realized I was dissociative. And another year to give diagnosis of DID. A year off from therapy we found a new one. She said she noticed switches the first session. I found as we talked to her....Feelings of relief and feeling like we are giving our secret away was so scary. As comfort level got better so did the ease to be who we were at any given time. T lets us be who we are as to ex T that really didn't let us be ...always wanted host and threats of ending session early if we couldn't be. Until she realized it was not us but her threats that caused more dissociation. Anyway I got off track....I agree that you should read...a good book for client and therapist is Coping with Trauma Related Dissociation. Here if you have questions. Safe journeys! !
