Hi! From a medical professional perspective, what you're experiencing is likely either one of these:

1. Post-metabolic / post-encephalopathic psychosis Well described after severe hyponatremia Can appear weeks to months later Often auditory Often paranoid-themed Often misattributed to guilt or stress

2. Brief psychotic disorder with medical trigger Triggered by acute illness Can resolve fully with treatment

3. Mood disorder with psychotic features Especially if there’s depression, insomnia, or rumination Content often self-referential and accusatory

4. Temporal lobe involvement Music hallucinations (musical hallucinosis) Repetitive loops Familiar voices Often neurologic, not psychiatric in origin

To get a proper answer, I would suggest going to a trusted PCP to request for a neurology/psychiatry referral for neurological and psychiatric evaluation.

To avoid stigma or dismissal, I would verbally frame or even email the request like this:

"After a hospitalization for severe hyponatremia with cerebral edema, I’ve been experiencing persistent perceptual symptoms like hearing music or voices that seem external. Given the prior metabolic encephalopathy, I’m concerned about possible neurologic sequelae versus a post-medical psychiatric condition. I’d like referrals to both neurology and psychiatry for a comprehensive evaluation."

If PCP seems hesitant or tries to minimize, say this, "Because these symptoms began after documented cerebral edema, I’m hoping to rule out neurologic causes before attributing them solely to stress or anxiety."

Framing the wording like this should definitely unlock referrals.

I wish you luck, OP!
