Anxiety already makes people feel like their brains are betraying them. For many people, it is not just nervousness or worry, but a persistent sense that their own thoughts, emotions, and physical responses are working against them. The mind races, the body tightens, and even simple situations can feel overwhelming or threatening. Over time, this constant state of alertness can erode confidence and create a deep sense of exhaustion. Scientists have long studied anxiety through the lenses of psychology and behavior, but new research suggests that something more tangible may also be happening beneath the surface, at the level of brain chemistry itself.
