ordeal

This term conveys a sense of prolonged suffering and psychological or physical endurance. It is typically used to describe experiences that are not just difficult, but emotionally draining or traumatic, often implying a feeling of being trapped in the situation until it concludes.

In a historical or legal context, the word refers to a specific type of trial based on the belief that a deity would protect the innocent from harm. This archaic usage is distinct from the modern sense of a personal struggle, though both share the concept of a severe test of character or survival.
