So I have a sorcerer from your typical TL3-4 fantasy world that gets dropped into modern American big city. While life-or-death combat and monsters are relatively familiar experiences to her, she feels overwhelmed by the dense populations, the imposing skyscrapers, and the constant noise of everyday life here. She can usually function with a low-level but unyielding stress in the back of her mind, but movie theaters, nightclubs, and similar loud environments may driver her to a panic attack.

This isn't a psychological condition, it's just a result of being trapped with more stimuli than she's ever known and is not uncommon among others like here. In time, she'll get used to her new world and buy off the disadvantage.

But does anyone know what disadvantage would model this? The closest I can find is Confused but its effects are far too broad.
