Multiple Voices in My Head: Can Anyone Relate?

Anyone else out there have multiple voices in your head that you know still has to be you but you can’t control? Like one I can tell is the little kid version of me that never felt loved or safe and was always scared, then there’s the voice that just took over saying the things my family did to me growing up after I cut them off, and then there’s the one that is nothing but anger and hatred at the whole world, and then the last one whose job it is to make me believe no one cares and I should just die. I can actually get caught up in arguing with them like they are other entities, but I know they are still me. I’ve tried explaining this to therapists before and all I got was a misdiagnosis of schizophrenia and another that just told me it was my CPTSD, but never got anyway of actually dealing with them.
