Carol Kirkwood has said she is fearful of cycling on the road after she was knocked off her bike by a car last year.
The BBC weather presenter, 59, had a “badly injured” left knee after the accident near Slough, Berkshire.
She told PA News agency of her injuries: “It was cut down to the kneecap and some of my nerves were hanging out. I sent a picture of it to my boss and he said it looked like I’d been attacked by a shark.
“But I had a brilliant doctor in Wexham Park Hospital who sewed me back together again.”
The former Strictly star, who was wearing a helmet at the time, was off work for three weeks following the accident.
Asked how her mental health had been affected, she said: “My confidence cycling on the road has gone to pot. I don’t do that now. I’m fearful now of cycling on the road.
“It was such a shock. I had dreams about it and I still do. Sometimes, I still get upset talking about it. It’s not on my mind all the time, but I dream about being hit.”
In May last year she posted a tweet thanking the police, ambulance and hospital staff who helped her.
Thames Valley Police responded to her message, tweeting: “Good to hear you are OK Carol Kirkwood and we wish you all the best with the rest of your recovery.”
She was a contestant in the 2015 series of BBC One’s Strictly Come Dancing, and was partnered with Pasha Kovalev.
The TV presenter was speaking as she promotes her debut romantic novel titled Under A Greek Moon.
The book is about a Hollywood actress embroiled in a scandal who returns to the Greek island where she fell in love with an enigmatic tycoon.
Under A Greek Moon is published by HarperCollins and available now.
