Longing is an emotional state characterized by a deep desire or yearning for something that is absent or unattainable. It often involves feelings of nostalgia or a sense of loss, where individuals may wish for a person, place, or experience that brings them comfort or happiness. This emotion can be triggered by memories, dreams, or unmet needs. People may experience longing in various contexts, such as for a lost loved one, a distant home, or a dream job. It can motivate individuals to seek change or connection, but it can also lead to feelings of sadness or frustration when the desired object remains out of reach.
