No medical advice or diagnosis, please. Just looking for information.

Hello. I am clinically diagnosed with DPDR, depression, anxiety, and some other things, but not BPD... or at least not yet, idk. I have a symptom that I am trying to narrow down the source of, so I am posting essentially this same thing in  several subs to tell what would be useful to ask my therapist about.

From time-to-time I hear the voices of my dead father or my abusive ex either criticizing me in ways they used to or telling lies to other people. They are inside my head--not schizo hallucinations--since I have been asked that many times. They don't stop until I talk back to them, argue against them, and defend myself in a way that is so aggressive that the real person would be made too mad to continue. If my response is any less than that, the voices don't stop.

I also practice conversations I have had in the past or expect to have in the future. I have done this practice as long as I can remember, for  at  least an hour a day. I am wondering if these voices are the same thing.

Does this happen to anyone else? The voices, I mean. If so, would you please give whatever details  you are comfortable sharing in the replies?

Thank you.
