Question...how did you block it out before?

reason I ask is because here where I live and work among the mental health profession....put simply dissociation is things like shutting out/blocking/ numbing. usually with dissociative problems the work is on breaking through that blocking\numbness... those that have dissociative problems have that ability to block out what they can not handle, its actually considered to be great progress when a dissociative no longer blocks out the voices. Instead they learn tools like learning grounding and using those voices to figure out what is triggering the voices, then using tools while still aware/in the present moment to take care of their self and that trigger (self nurturing and grounding)...in short no longer depending upon dissociating to get away from what triggers them into dissociating....

example one day at work the voices got louder. using my therapy tools I found a quiet area and used my breathing exercises and grounding exercises, then I took the time to think about what was happening...I was at work, dealing with a drunk abuser. this reminded me of an abusive situation as a child I had not been able to handle. now I knew what the trigger was i could take care of myself. I went back to my desk and told the abuser we had to end the meeting due to he was not sober and able to take part in the meeting with clarity. I scheduled another appointment date and had security escort the person off the property. The voices then quieted down because the triggering situation was taken care of and I did not need their help to do so (dissociating)

I know its hard to believe but its a good thing that you no longer rely on dissociating and can now hear your voices. it shows great progress and healing.

my suggestion Talk with your treatment providers or a treatment provider in your off line location, they can help you learn what is triggering you and the voices , learn things like grounding/self care/self nurturing that can help you to take care of the situation with out having to use your dissociative skills to block out the voices,
