Fergie has given an update on her recovery from her eight-hour cancer surgery and revealed it had been a "scary" time for her daughters, Princess Beatrice and Princess Eugenie.
Speaking on her podcast Tea Talks, Sarah, Duchess of York, said she was "recuperating at home" following a single mastectomy operation recently.
The 63-year-old discovered she had an early form of breast cancer during a routine mammogram and is currently being supported by the royals, including her ex-husband Prince Andrew.
She told the podcast, which she hosts with Sarah Thompson, how her daughters had responded to her diagnosis and subsequent surgery.
And she revealed: "'I think it's scary for any family member out there, you really start to look at your own demise. It's a wake-up call, and you think, how am I going to deal with this?"
Fergie also revealed how Beatrice had picked out her outfit for the podcast recording and added: "I have to say it's really just extraordinary to come to terms with a new you.
"You cannot be complacent with yourself or life or how lucky you are. It's really important that my father was right: The show must go on. But be mindful of each word you say, be gentle with yourself and people, and be very grateful.'
Sarah also said it has been "moving" to receive a note saying: "You are the strongest, bravest person I know and it’s because of you that I'm still here."
She said the support she has received has given her the strength to "go forward". She added: "The most beautiful, beautiful flowers have arrived. There's letters, there's cards, and it's just been an outpouring of kindness.
"And it's so much so that you can't… you know, the mind has made up so many games before this thinking everyone believes what they read in the newspapers, and then with all this outpouring of love, it's like almost it's everybody's eulogies to me.
"I know, and I'm here, and it's really amazing the love that I'm getting from the entire nation.
"I mean, it's just unbelievable. Just extraordinary. And it's not just the nation, but it's globally and people have been beyond, so yes… just blown away really.
"And that is something that has also completely given me strength to go forward because I won't let people down. Well, I won't let myself down."
Speaking about her experience, Sarah said: "It's not bravery. It's not courage. It's about understanding that you're not going to feel as you did for a bit. So don't try and be a superhero.
"Take many steps, have the cup of tea. Trust people; very important not to be complacent with every single thing now."
The Duchess said she would love to have "a really super duper mastectomy bra that actually looks fab because it makes you feel feminine and great".
