“In the life cycle of an intense emotion, if it isn't acted upon, it eventually peaks and then decreases. But as Dr. Linehan explains, people with BPD have a different physiological experience with this process because of three key biological vulnerabilities (1993a): First, we're highly sensitive to emotional stimuli (meaning we experience social dynamics, the environment, and our own inner states with an acuteness similar to having exposed nerve endings). Second, we respond more intensely and much more quickly, than other people. And third, we don't 'come down' from our emotions for a long time. One the nerves have been touched, the sensations keep peaking. Shock waves of emotion that might pass through others in minutes keep cresting in us for hours, sometimes days.”
