"Whatever [viewers] get from this is their choice," she says. "I've made mistakes, I'm human ... if you can relate to my ways and my demons then I hope it helps, but it's about them not me."
In the six-part series, the Dutchess of York sets out to put her life in order after many publicized set-backs like her divorce to Prince Andrew. Along the way she deals with her weight, finances and relationships by receiving help from experts like Dr. Phil and Suze Orman. Dr. Phil calls her "emotionally bankrupt" in an early episode and Ferguson admits to us he was right.
While the series suggests she's looking to find out who the real Sarah Ferguson is, the 51-year-old Dutchess says she's learned she was always there.
"I'm actually the same person, I've just allowed Sarah to be the true person," she says. "I'm cheeky, I'm naughty, I'm funny, I'm feisty, I'm strong, I'm angry, I'm sad, I'm grumpy — I'm all those things, but now I'm OK with all of those things."
