The Duke and Duchess of Sussex tied the knot at Windsor on May 19.
Royal expert Duncan Larcombe said that he felt “desperately sorry for Meghan” in the initial period of adjusting to Royal Family life.
Mr Larcombe told Fox News Digital: “Harry clearly never really wanted to admit to her what was actually going to be involved with the Royal Family.”
Mr Larcombe said he spent an extensive amount of time covering the early years of William and Kate’s relationship.
She said: “I would sit up at night, and I was just like I don’t understand how all of this is being churned out and again I wasn’t seeing it.
“But it’s almost worse when you feel it through the expression of my mom or my friends or them calling me crying just like ‘Meg, they’re not protecting you’.”
Meghan described feeling “really ashamed to say it at the time”, particularly to her new husband.
She continued: “But I knew that if I didn’t say it that I would do it, and I just didn’t…I just didn’t want to be alive anymore.”
She then claimed she “went to the institution” looking for help, adding that “I’ve never felt this way before and I need to go somewhere”.
She then told Oprah: “And I was told that I couldn’t, that it wouldn’t be good for the institution.”
In the wake of the interview, Buckingham Palace said the couple, along with their son Archie, would “always be much loved family members”.
In a statement, the palace added: “The whole family is saddened to learn the full extent of how challenging the last few years have been for Harry and Meghan.”
