The mother of Olympic champion Kelly Holmes had to watch her daughter's triumph on television at home, because she has not got a passport.
Kelly Holmes ran a personal best to take her Olympic gold
Holmes won gold in the 800m on Monday, becoming Great Britain's first track and field champion of the Athens games.
Her mother Pam Thomson, from Kent, said she had never applied for a passport and did not know if she could have coped with the tension in the stadium.
On Tuesday, she said her celebrations had left her feeling worse for wear.
Holmes, 34, who is in her third Olympics, knocked more than a second off her personal best time to win the 800m.
Ms Thomson spoke to reporters when she left her home in Hildenborough, near Tonbridge, to walk her dogs.
She said: "It was very nerve-wracking.
"Kelly spoke to me last night and then I went to celebrate - we had a good time."
She said her daughter would not have been able to enjoy the same sort of celebrations, because her campaign to win a second gold in the 1500m starts on Tuesday evening.
"She didn't do much because the 1,500m has still got to come.
"The only question is whether the hunger is still there; but it's her favourite event."
She said she was going to speak to her daughter to ask how she was and whether she had been able to get any sleep.
Ms Thomson said one of the dogs she was walking, Harley, had played a role in the success.
"Harley used to be her training partner; he used to drag her along when she was young, and make her run," she said.
Shown a newspaper with her daughter's celebrating picture on the front page, she said: "Look at her face - she won't like that picture."
