Three days in, severe but new

Amara, 26, was well until three days ago, when she suddenly began expressing a fixed belief that her downstairs neighbour is controlling her thoughts through the building's wiring, alongside brief episodes of hearing whispering that comes and goes. Her mood is intensely anxious and fluctuating. This is her first such episode, occurring during an unusually stressful week at work. No history of substance use or medical illness has been established yet.

Based on three days of symptoms alone, what is the best classification decision?
