you asked if what you posted sounded like anyone else...yes this sounds like many things in me. in me my own treatment providers called what you posted depression, bipolar disorder, psychosis and many other things too.

the symptoms in me that were called DID was not the voices. it was having two or more special kind of alters that constantly took control and affected all aspects of my life since before I was 5 years old....having a special kind of memory loss in which the two or more alternate personalities knew what went on and I the aware person did not. with me the time loss did not increase over time. it was contingent on when I dissociated (got triggered by something and that triggering resulted in the alter whose job, purpose, reason for being took control to handle that situation), these alters taking control happened in all aspects of my life not just when I was alone and there was no hiding it for it was out of my control.

for me the hearing voices without all the other DID associated problems was called psychosis, bipolar disorder and other normal things like stress, sleep deprivation.
