He recalled feeling bedridden by depression and having to give himself pep talks before he went on air in a bid to maintain his public image.
“Like everyone who suffers from depression, it tends to come and go,” he said. “I didn’t want to get out of bed and didn’t want to go to work and didn’t want to talk to anyone.
“It might be something to do with the fact that I wasn’t completely happy at work, but that wouldn’t explain how overwhelming it was.
“The problem is you are a familiar face, and you have to maintain a public image. Before going on the air, a few minutes before 6 o’clock, I had to tell myself, ‘OK, you’ll be fine, you just have to do it’.”
The journalist, who has presented News at Ten for 18 years, said taking up boxing had helped him manage his mental health struggles.
“You are in some sort of a personal zone,” he said. “The whole thing is about relaxing even though it is fitness.”
Elsewhere in the documentary, he said he believes “keeping busy is one of life’s best secrets”, and that he would take up more work if he left his position at the BBC.
“When the time comes for me to quit the job – or for them to let me go – I don’t want to put my feet up and do nothing. I’ll be looking for other work, because keeping busy is one of life’s best secrets,” he said.
Huw Edwards yn 60 will be broadcast on 29 December.
