Whats psychotic depression?

Psychotic: Depression is any depressive episode that includes psychotic symptoms like hearing voices, seeing visions or feeling paranoid.

Depression: Psychosis in depression usually involves delusions of guilt or annihilation or of negative content, or hallucinations of derogatory nature such as voices telling the person he/she is bad or deserves to die or is worthless.

Dr Passer and another doctor agreed

Rare but possible: Rarely, a clinical depressive episode is so severe that low mood is accompanied by psychosis, often seen as a loss of reality with derogating auditory hallucinations, paranoia and sometimes suicidal thoughts. This is treatable, but needs to be dealt with immediately by seeing a psychiatrist. If in danger of harming self or others, then first seek care at the emergency room or call 911.
