Susan Williams attributed the actor's decision to Lewy body dementia over depression.

Just before Robin Williams died, his wife got to tell him, "I forgive you 50 billion percent, with all my heart. You're the bravest man I've ever known."

Speaking to Good Morning America in a prerecorded interview that aired Nov. 3, Susan Williams explained, "We were living a nightmare."

The sit-down, filmed in August, was her first interview since her late husband's death on Aug. 11, 2014.

Susan Williams denied her husband was "suicidal," insisting his decision to take his own life was due to "what was going on inside his brain, the chemical warfare that no one knew about." Among his health problems were a diagnosis of the early stages of Parkinson’s disease and deepening anxiety, along with depression and a slew of other undiagnosed symptoms.

The week of his death, doctors were planning to check Robin into a facility for further neurocognitive testing, primarily because of an incident during which Robin hit his head and bled heavily. After his death, the coroner's report pointed to a debilitating brain disorder called Lewy body dementia, a type of dementia closely associated with Parkinson's disease.

Following the release of the coroner's report, Susan made the connection to the injury: "Lo and behold, one of the symptoms: Their vision is affected. Spatially, depth, the ability to recognize, identify objects."

Susan said that Robin, who was sober for the last eight years of his life, was "just disintegrating before my eyes. Lewy body dementia killed Robin. It's what took his life. ... [He was losing his mind,] and he was aware of it. He was keeping it together as much as he could, but the last month, he could not. It was like the dam broke."

When asked whether suicide was the beloved actor's way of taking back control, his widow responded with a yes. "Believe me. I've thought about this, of what was going on in his mind, what made him ultimately commit, to do that act. And I think he was just saying, ‘No.’ "

She added, "I don't blame him one bit."
