"The Bitter End"

"The Bitter End" is a phrase used to describe the final, often most difficult part of a challenging situation or process, where success feels unlikely or hardships seem unavoidable. It acknowledges the emotional or physical toll experienced before resolving or overcoming an obstacle. The term originates from the idea that, just as a drink's "bitter end" is its last, most intense taste, the phrase symbolizes reaching the final, often toughest stage of an endeavor. It emphasizes perseverance through adversity, implying that endurance is needed until the very conclusion of a difficult journey.
