Kirsty Gallacher hit "rock bottom" after her divorce.
The 43-year-old presenter split from Paul Sampson - the father of her two children - in 2014 and admitted her "horrific" marriage breakdown was hard to cope with and she thinks she pushed herself too hard.
She said: "Divorce is horrific. I've had a tough few years. I hit pretty much rock bottom at one point.
"My poor body and brain has gone through it. I've not coped very well.
"And I was trying to be a great mum and keep it all going. I was pushing myself too much."
After her divorce, Kirsty - who was banned from getting behind the wheel for two years after being arrested for drink driving in 2017 - romanced Danny Cipriani, Laurence Fox and Jack Whitehall and though all her romances were "lovely", she knew they weren't "right" for her but persisted because she didn't want to be alone.
Speaking to Natalie Pinkham on her 'In The Pink' podcast, she said: "When you split up with a long-term partner, you feel like you have to catapult yourself into another relationship.
"That's what I did. They were lovely relationships, but they weren't right.
"It's part of the learning curve, but I was scared to be on my own."
The former Sky Sports presenter regrets not listening to advice from her brother-in-law Russell Brand, who has two children with her sister Laura.
She explained: "Russell said, 'Kirsty, I think you need some time on your own'.
"I thought, 'No I don't!' So I didn't. Now, sorry Russell, you're correct."
