Fearne Cotton stopped doing some TV work because she found the reaction to being on the box "so overwhelming".
The 40-year-old radio presenter - who has hosted the likes of 'Top of the Pops’ and been a team captain on ‘Celebrity Juice’ - now prefers to take on "safer projects" instead.
Speaking on ‘The One Show’, she said: "I did have a tricky period where I had to reassess everything.
"Some of the other stuff I used to do, I've had to step away from for now,
"At the moment it feels nerve-wracking, a scary prospect so at the moment I'm doing things that feel safer.
"The reaction we get from being on TV ... I found that so overwhelming that I started to dull myself down.
"I was diluting my personality because I was so scared of the reaction."
The media personality previously took to social media to tell fans about her anxiety.
In April last year, she wrote: "Anxiety crept up on me as my head hit the pillow and I just couldn’t get into a deep sleep.
"Recently I have been sleeping so well, so last night was disappointing but I’m not going to let one bad night set me back. If anything it’s a sign I have more important work to do. More self inventory, more self compassion, it’s a life’s work.
"If you experience anxiety too, don’t compare yourselves to others. It’s easy to do, I know!
"It's easy to imagine everyone else copes just fine but it’s not helpful to use comparison in these moments.
"Be kind to yourself always."
