Arbus experienced "depressive episodes" during her life similar to those experienced by her mother, and the episodes may have been made worse by symptoms of hepatitis. Arbus wrote in 1968, "I go up and down a lot," and her ex-husband noted that she had "violent changes of mood." On July 26, 1971, while living at Westbeth Artists Community in New York City, Arbus took her own life by ingesting barbiturates and slashing her wrists with a razor. Marvin Israel found her body in the bathtub two days later; she was 48 years old.
