Susan Schneider, well-known actor Robin Williams' widow, is finally ready to discuss her final months with her husband. On Tuesday, she revealed that, in her opinion, it was not depression that lead to the "Good Will Hunting" actor's suicide, but rather his Lewy Body Dementia diagnosis. Now, Schneider says Williams, 63 at the time of his death, was given just a few years left to live.

In an interview with ABC's "Good Morning America" the Academy award-winner's wife revealed that Williams' disease is "what took his life." As was reported by Buzzfeed, Schneider said he spent his final months suffering from dementia, paranoia, hallucinations and depression -- all symptoms of Lewy Body Dementia, which he was not diagnosed with until after his death. She said his health was rapidly deteriorating, adding that they "were living a nightmare." According to Schneider's account, Williams' doctors were planning to have him checked into a facility where he would undergo neurocognitive testing. She also shared with ABC that the actor was given less than three years to live. 

"They would've been hard years. And it's a good chance he would've been locked up," she said. 

During the interview Schneider said that while her husband had previously struggled with both drug and alcohol addiction he was clean and sober for close to a decade when he died. She said he tried his hardest to maintain control, but his disease was taking over fast. Schneider recalled the feeling that he was "sinking," sharing a story in which she found him bleeding profusely on the floor of their home. When she asked what had happened Williams simply replied that he had "'miscalculated.'" When asked whether or not she felt her husband was trying to regain control of his life by committing suicide, Schneider admitted she felt that was the case saying, "In my opinion, oh yeah. I think he was just saying no."

On Tuesday, Schneider told People magazine her husband had been depressed, but said that wasn't what pushed him to commit suicide in August 2014. She told the publication that his disease, which had gone undiagnosed, left him anxious, delusional and struggling to move his body like he once could. Schneider said the depression was a "small" symptom of his Lewy Body Dementia. She claimed she has spent the last year since his suicide trying to better understand what they were dealing with, adding that doctors told her "'Robin was very aware that he was losing his mind and there was nothing he could do about it.'"
