Charlie Dimmock's agent has described how the presenter has been struggling to cope since her mother and stepfather disappeared in the Asian tsunami.
Ms Dimmock's mother Sue Kennedy, 59, and her stepfather Rob, 60, were in Phuket when the tsunami hit.
The couple, from West Wellow, Hampshire, are still missing.
The 38-year-old TV gardener made her first public appearance on Friday since the news. Her agent Debbie Schiesser said that took "a lot of courage".
Ms Schiesser said: "It is very upsetting for her. It has been too soon for her to come to terms with it.
"She is coping day by day at the moment. We have promised her that we will protect her."
She added that Ms Dimmock "is a very private person - one of the most private people I have met".
