my suggestion would be instead of trying to force the alter who's sense of agency is to prevent the telling of the secrets. just let things happen naturally.

here in my location dissociation is a natural response to anything triggering, therapy is where people go to a therapist and talk about their problems which trigger them and which they are not able to solve on their own.

what that means is just due to the natural course of therapy a person with DID is going to naturally switch into the alters who's sense of agency it is to take care of that trigger.

(sense of agency is a new diagnostic term for DID, that means dissociative alters of the person they reside with in have their own ways of being, their own jobs, purposes, and reasons for being created, what causes them to take control, things that make them distinguishable from each other and the one that they reside with in, how much control each alter has...)

for example rainy was my dissociative alter who's sense of agency was sadness and fear of storms. thats why she was created to take care of those situations and when she would take control, it was her job, purpose reason for being created to take care of any situations that caused me sadness and fear of storms.

now heres how DID alters work in therapy, my treatment provider and I are talking and we end up talking about a storm or something sad, the natural response to this is naturally switching into the alter Rainy. then the therapist is naturally talking with Rainy.

no guesswork on me, no stress on me, no fighting against Frown to tell the therapist about the others( for the purpose of this post I will call Frown because their actual name would get filtered out of the post due to the sites profanity filter). each alter just tells about their self during the normal process of therapy...

the funny part is when I did tell my therapist I wanted to tell her about others but was unable to she smiled and said thats ok thats already been happening. getting the diagnosis doesnt change what has already been happening. with out my even knowing she has already been talking with my alters. Im guessing if you and your therapist are talking about anything of a triggering nature then you dont .......neeed..... to tell your therapist anything about the others, they have already been doing so their self. its just already happening naturally due to what the disorder is.
