hmmm interesting likewater. I have lots of voices in my head too and images. Mine don't have names, i'm not DID, but I still believe the voices in my head are in fact my own, aspects of myself that i've sectioned off and refuse to incorporate into myself. I have a girl who screams and tells me to cut, kind of a daring one (masculine) low voice, who dares me to drive my car off bridges or crash into trees etc. There's my alcoholic voice thats kind of annoying, i get him to shut up easily, i've learned how to manage him. etc etc etc.

I have no help to offer, just saying you aren't alone in this. I haven't told my T yet either, i've lived with the voices so long i didn't realize it was "different" until recently.
