deplete

This term conveys a sense of gradual exhaustion or a steady decline toward emptiness. It is frequently used in technical, environmental, or economic contexts to describe the consumption of finite resources, such as minerals, funds, or ozone, where the focus is on the diminishing quantity of a stock. When applied to people, it describes a state of total physical or emotional drainage. It suggests a void where energy once existed, often implying that the depletion was caused by an external demand or a grueling task rather than a natural sleep cycle.
