This Invisible War Inside: How Anxiety Rewires Your Heart, One Moment at a Time Anxiety isn’t just a persistent worry or a fleeting stress response—it’s a silent, scaling force reshaping your inner world, heart by heart. While often invisible to outsiders, this internal struggle profoundly rewires both mind and body, altering physiology, emotional responses, and long-term health.
