Meghan Markle's father thinks some of her struggles could have been combatted with his help.

Thomas Markle, who has been estranged from his daughter since around the time of her wedding, appeared on "Good Morning Britain" on Tuesday and addressed the Duchess' explosive interview with her husband Prince Harry and Oprah Winfrey.

Among the revelations shared during the two-hour-long sit-down is that Meghan, 39, was facing suicidal thoughts amid intense criticism by the press.

Thomas, 76, however, feels that he could have offered his daughter help during that time.

"Had I known she was having psychological problems, I would have been there for her," he said. "Biggest problem here is she's pretty much ghosted all of her family on her mother's side and my side."

Thomas said it "upset" him to learn that his daughter had such dark thoughts during her pregnancy. The Duchess also claimed that she was barred from receiving help, as she was told it would reflect poorly on the royal family.

"It would have been easy for her to reach out to me and any of the rest of her family -- who she claims she doesn't know," Thomas said on "GMB." "But the other thing is that I would think that she could turn to her husband."

"The bottom line is she didn't lose me. She made a statement saying she lost me. She didn't lose me," Thomas added. "I would have always been there for here. I'm there for her now if she wants me."
