I basically have schizoaffective disorder and experienced heavy bouts of psychosis for about 5-6 years until I summoned the strength to find an alternative drug that worked for me as the drug that was prescribed to me obviously wasn't doing the job. I've been fine for about 8-9 years now and I do recommend getting a notebook and making a note to get you on the right stuff(medication) as soon as you can as this can help with the voices.
In the meantime there is no debate within the medical community that the voices aren't real but hallucinations generated by a failing mind that fails to handle serotonin or dopamine levels in the brain. You start seeing things and patterns people don't see your limbs may move of their own free will it's quite disconcerting.
This has never sat well with me as I've had a conversation with a voice that identified herself as "Samyaza" was incredibly insightful and intellectually beyond me in terms of malicious intent, intellectual capacity, ability to manipulate, lies and undermining. I understood that "Samayaza" asked for my permission to hear voices in the first place during my pre-psychotic phase that I only understood in my emotional space as I hadn't heard voices before. The first time I heard voices it was a complete shock I had been playing a game on the computer, doing my job and doing all of the "normal" stereotypical things a person does. The voices influenced me in ways you couldn't understand and within a few hours I decided to lock myself outside of my apartment without the key and without any means to get back in without shoes on. They effectively reduced me to a jibbering wreck within a few hours.
As someone who suffered this for sometime I recommend music therapy, journaling and not trying to actively to fight the voices as they are tricky things they act as your inner monologue, trick you, lie to you, get you to do abnormal things through knowing how your brain works and often act in an intellectual capacity far exceeding your own capability. Don't do what they tell you to do and don't not do what they tell you not to do just do you in as far as you can do you.
Just imagine that you had a bad friend who sits on your shoulder who could change their voice on you. You'd try to brush them off your shoulder. Try acknowledging that the voice is not your inner monologue which is all your should be hearing in your mind and try owning the space in your mind and your emotional space.
I sincerely wish you the best on your self-rediscovery journey and hope that the takeaways from my story help you.
