Final answer:
The emotional state described is linked to grief and may lead to major depression, which includes prolonged sadness and other symptoms like problems with sleep and concentration.
Step-by-step explanation:
The emotional state of longing and deprivation that is characterized by a deep sense of loss is often associated with reactions to grief following the death of loved ones. This intense emotion may lead to symptoms of major depression, a mental illness characterized by sustained periods of sadness, among other symptoms such as changes in sleep, appetite, feelings of hopelessness, lack of energy, difficulties concentrating, and thoughts about death. Moreover, certain psychological theories suggest that deviations from homeostasis can create physiological needs that result in psychological drive states that motivate behavior to meet the need and return to homeostasis, which could influence one's emotional state.
