TV presenter Louise Minchin has said she was in a "high state of alert all the time" during her stalking ordeal, while her teenage daughter Mia said she was left "terrified" and "in floods of tears".
Ex-soldier Carl Davies, 44, was sentenced to two years and eight months in December last year after posting multiple "intimidating" messages "intended to maximise fear and distress" to the broadcaster and her daughter's social media accounts over four days between July 14 and 17, 2020.
The I'm A Celebrity... 2021 contestant, who left BBC Breakfast in September last year after 20 years, told ITV's current affairs show Tonight that the experience terrified her.
She said: "It was very clear from the messages that this person knew exactly where we lived and had stood outside our front door.
"To say I was frightened just doesn't really touch the surface.
"You are kind of on this high state of alert all the time. You don't know who they are so you don't know that that person standing next to you isn't them."
Speaking for the first time about the ordeal, Mia said: "I'm logged into mum's Instagram account and suddenly loads of messages started coming.
"They were all kind of just really offensive, calling us not very nice names and then they got much more graphic. It was the kind of actions that he wanted to do against me and mum which got really personal and they weren't nice to read at all.
"I was kind of terrified... shaking. I think my heart was beating really fast. I didn't sleep all night. The entirety of the next day I was in floods of tears."
She added the experience has had a lasting effect, saying: "When I'm walking, I'm very conscious of who is behind me, especially not to have my headphones in if it's dark and there's no one else around."
He had previously been convicted in 2017 of stalking another woman and for biting his father on the arm in 2019, the court heard.
ITV Tonight - Louise Minchin: The Truth About Stalking is on ITV on Thurday at 8:30pm.
