Kate Humble has been left "doubled over" in pain due to the grief she feels over the death of her father.
The former 'Springwatch' host's dad Nick passed away earlier this year at the age of 82 and Kate revealed she finds revisiting the memories of her dad emotionally overwhelming because her grief is still so raw.
And when she is out walking in the countryside, the wildlife presenter often finds her mind wandering to memories of her father.
In an interview with Saga magazine, Kate shared: "Being on my own and being in the countryside, it doesn't matter that I'm wailing - and it has really helped. In that time, I'm not lonely. I have this luxury of solitude and time just to remember. The lovely thing about walking is I can spend that time with my dad."
Speaking about the physical affect her grief has sometimes had on her, she added she has sometimes been "doubled over" in pain "sometimes in company but often on my own and often when I'm walking".
Kate was always very close to her father Nick, who had a career with IBM, and always respected his "hard-working" and "principled" character traits and she admits they share a "similar temperament".
The 50-year-old presenter - who grew up in Berkshire with her father and mother Diana - said: "Dad was incredibly hard-working, stubborn, very principled and hot-tempered - all of which I am, too.
"We'd argue because of our similar temperament, but I did, and still do, worship my dad. He was the best storyteller - no one could read Winnie-the-Pooh like him, with all the different characters' voices.
"Mum was much calmer and the peacekeeper of the family - she was the family anchor."
Kate - who has been married to television Ludo Graham since 1992 - has no children of her own but she has no regrets because she always knew being a mother was "not for her."
She said: "I know motherhood was not for me and, literally, it bypassed me. Not being a mum has never been an issue."
