Susan Williams, the widow of Robin Williams, sat down for a rare interview today with Good Morning America.
Through tears, Susan shared the final conversation she had with the late Oscar winner, who stunningly took his own life in August 2014.
"I was getting in bed and he came in the room a couple of times … and he said, "Goodnight, my love, " " Susan recounted.
"And then he came back again. He came out with his iPad and he looked like he had something to do. And that was like, "I think he"s getting better."
"And then he said "goodnight, goodnight." That was the it."
Susan then told co-host Amy Robach that in the weeks and months months leading up to Robin"s death, the star was diagnosed with the early stages of Parkinson"s Disease.
“My best friend was sinking,” she said of Robin’s reaction to the illness, which included an incident when he bloodied his head in the bathroom, yet was unable to tell her what happened.
Williams checked himself into rehab about one month prior to his death, following a long battle with alcohol and drug addiction.
However, Susan told Good Morning America that Robin had been sober for eight years – and it was neither the addiction nor depression that resulted in his death.
"Lewy Body Dementia killed Robin," she said of the illness that shares characteristics of both Alzheimer"s and Parkinson"s disease.
"It"s what took his life."
