The four-part docuseries follows Sheeran’s rise to fame as well as his family life and personal struggles.
In the video, Sheeran credits Edwards with helping launch his career, and is seen breaking down in the back of a car after learning of his death.
“Loss: it just took over my life,” Sheeran says.
The Shape of You singer’s wife Cherry Seaborn also appears in the documentary, saying her husband “hasn’t had time to process and be at peace with his thoughts”.
Sheeran recently revealed that Seaborn was diagnosed with a tumour while she was pregnant with their second child.
“At the start of 2022, a series of events changed my life, my mental health, and ultimately the way I viewed music and art. Writing songs is my therapy. It helps me make sense of my feelings,” the singer said while announcing his forthcoming album, Subtract, earlier this month.
Edwards’ mother Brenda recently revealed that Sheeran stayed with their family for a week after her son’s death, “looking after” them.
“There wasn’t anything that he wasn’t sorting out and doing if we needed anything, and everybody has been so, so wonderful and so supportive,” she said.
After Edwards died, Sheeran posted a tribute to the MBE on his Instagram page saying that he “would not be here without him”.
“A star’s light shines for millions of years after they go, and his will continue to light up every dark moment, we are all witnessing his power,” he wrote.
The Sum Of It All will be released on Disney+ on 3 May.
