In the claustrophobic eleven-minute runtime of "A Pure Portion of Anxiety," director Chae Yu crafts a visceral and unsettling portrait of a woman trapped in the grip of an overwhelming panic disorder. The film follows its unnamed protagonist as she navigates a single, ordinary day that becomes a labyrinth of escalating dread. Every mundane interaction, from a ringing phone to a crowded street, becomes a potential trigger, transforming her own body and home into a source of terror. Her motivation is simple yet profound: to simply exist without the crushing weight of her own mind. The central conflict is an internal war against an invisible enemy, a battle fought with shallow breaths and a racing heart in the quiet spaces between moments. This short film masterfully blends psychological horror with stark realism, using a tight, immersive perspective to place the viewer directly inside the character's spiraling consciousness. It is a raw, empathetic, and deeply unsettling exploration of what it means to be consumed by a pure, undiluted portion of anxiety.
