US TV presenter Savannah Guthrie will return to the Today show on 6 April, two months after her mother's disappearance.
In her first interview since Nancy Guthrie went missing, she said she "can't not come back" to the show "because it's my family".
"I don't know if I can do it. I don't know if I'll belong anymore, but I would like to try," she added.
Nancy Guthrie was last seen at her home near Tucson, Arizona, on 1 February. Investigators believe she was taken against her will, but have not arrested a suspect.

She told Kotb that she wants to smile again, and that "when I do, it will be real. My joy will be my protest".
Craig Melvin, Savannah Guthrie's co-host said the programme "cannot wait to welcome her back with open arms".
A nationwide search for Nancy Guthrie has unveiled several leads, including discarded gloves, DNA evidence and alleged ransom notes, but it has not lead to any major progress.
Since her disappearance, Savannah Guthrie and her siblings have posted multiple videos on social media, including making direct appeals to their mother's captor.
They are offering $1m (£760,000) reward for information that leads to her return, in addition to a $100,000 reward offered by the FBI.
