"I miss Michael every day," Corinna said in the documentary.
"But it’s not just me who misses him. It’s the children, the family, his father, everyone around him," she added.
"I never blamed God for why this happened. [The accident] was just really bad luck, all the bad luck anyone could ever have in their life."
Michael Schumacher was skiing with son, Mick, in the French Alps on December 29, 2013, when he hit a partially covered rock.
Although he had not been skiing very fast at the time,he lost control and was thrown over 10 metres, striking his head on another rock.
In 2018, Schumacher's rescuer, mountain cop Stephane Bozon, opened up about the accident.
"The first responders said that because the accident site was next to the slope, it was difficult for them to transport him carefully and cautiously," he told German news outlet FOCUS.
"It was clear that it was very serious, otherwise we would not have used the helicopter. Mr Schumacher was lucky [to survive]."
