I had a n on verbal alter that used a type of sign language with my therapist. when I found out about this alter I was a bit confused, but my therapist reminded of something. that in order for the alters to be DID \dissociative type they had to have their own jobs, purposes, reasons for being. that they were a special kind of alter that did not share the same things as me, therefore it wasnt anything to worry about when I discover each of my alters were not like me and thought differently than me and had other ways of dealing with things like me. for this alter this means she for what ever reasons was non verbal and used my cultures symbols\signs as a way to communicate.

exactly how this came to be that this alter was non verbal and had a different way of communicating was because my alters held memories / trauma's \ emotions that I could not handle. I was told and threatened during extreme traumatic events to not tell what was happening but yet I was being taught in school and home to follow that feeling when I felt something was wrong, say no and go tell.

this traumatic event conflicting with what I was being taught resulted in my very young mind that was unable to handle the trauma and not tell\tell conflict split to form an alter that literally could not tell in verbal ways what was happening. when it was finally understood that it was ok to tell, this alters job, purpose,reason for being was no longer needed so she integrated with me to become one whole person with me.

only you and your treatment providers can say how and why you have this deaf\mute alter.

my suggestion talk with your treatment provider, they will help you with this in ways that we online can not.
