Heartbreak is an emotional response to the end of a romantic relationship or the loss of a loved one. It often involves feelings of sadness, grief, and longing. People experiencing heartbreak may find it difficult to concentrate, sleep, or engage in daily activities. The intensity of these feelings can vary based on the depth of the relationship and the circumstances surrounding the loss. Physiologically, heartbreak can also affect the body, leading to symptoms such as chest pain or fatigue. This phenomenon is sometimes referred to as broken heart syndrome, which can occur after significant emotional stress. Healing from heartbreak typically takes time and support from friends and family.
