Britain's Duchess of York said being snubbed for the royal wedding was "so difficult."
The duchess—real name Sarah Ferguson—was not invited to Prince William and Princess [sic] Catherine's big day last month after she was caught out by an undercover reporter offering access to her ex-husband Prince Andrew in exchange for money.
Speaking on The Oprah Winfrey Show, she said: "I went through the phase of feeling so totally worthless and that [it] was quite right they didn't invite me. Why would they—why would they invite me?
"I felt that I ostracized myself by my behavior, by the past, by living with all the regrets of my mistakes, that I sort of wore a hair shirt and beat myself up most of the day thinking and regretting why did I make such a mistake? Why have I made so many mistakes?"
Sarah watched the wedding—which her daughters Princesses Beatrice, 22, and Eugenie, 21, attended with their father Prince Andrew—on television in Thailand and revealed she was in constant contact with her family while they were getting ready.
She said:"I wanted to be there with my girls... to be getting them dressed and to go as a family. Also, it was so hard, because the last bride up that aisle was me.
"When Andrew went with the girls, we were talking all morning and he was saying, 'It's okay. Just remember we had such a good day. Our wedding was so perfect.'"
