Found the graph. Thanks.
Well, I don't have a DID, not sure about DDNOS.
What happens is, under stress/extreme stress my voice charchteristics, along with an attendent attitude, can change. And in certain cases when the stress - either externally or internally stimulated - the voice charachteristic/attitude gets stuck. Some or most of the time.
Others have noticed this about me too. Its all me, I remember everything, no problem there. When I was seeing my first T, I told him I wanted to "find my true voice". He seemed to know exactly what I meant.
As a young adult, I didn't like my "native" voice (or myself). So, I worked to change it. Is this voice/attitude shift part of the external shell/person I created to deal with 'creating a life for myself'?
Had been unable to talk about this before, so just thanking everyone for helping me get to the point where I can. Very helpful for me to explore this.
