The claim came in People, a United States magazine, to which five of her friends spoke anonymously in reaction to coverage of the duke and duchess in recent months, which has included reports of difficulties over staff and claims of a rift with the Duchess of Cambridge.
Another said: "We worry about what this is doing to her and the baby".
A pal said: "After she and Harry got back from honeymoon, Meg sat down and wrote Thomas a long letter".
The awards "celebrate the achievements of injured or ill service personnel who have used sport and adventurous challenge as part of their recovery and rehabilitation", Kensington Palace tweeted ahead of the event.
Meg's so-called relationships with her father, Thomas Markle, and half-siblings. He's never called. He's never texted.
A source told the magazine: 'Meg and Harry were still so focused on getting [Thomas Markle] to London.
The friend alluded to Thomas not picking up calls from the Duchess after he had a heart attack.
He told Good Morning Britain in December that his daughter had ignored multiple messages and daily texts from him.
While at the reception overnight, Meghan was overheard gushing about her husband telling one of the guests, "He's going to be the best dad". It was like, "Please pick up".
The pregnant royal used a black marker to scrawl handwritten notes on the food parcels, such as "be strong" and "you are loved". Please stop victimising me through the media so we can fix our relationship'.
"In the room she made up for me, there was a candle lit by the bed, slippers and a robe", she detailed.
About that, the insider claimed that Meghan "absolutely loves her father but feels betrayed" by his many interviews on TV and in the online media. "Please stop victimizing me through the media so we can fix our relationship.' Because every time her team has to come to her and fact-check something [he has said], it's an arrow to the heart", the insider explained.
The Duke and Duchess of Sussex were all smiles at an awards ceremony honouring military veterans - a day after it emerged Meghan had made an emotional plea to her father to stop his "victimising".
When I see her at engagements, folks will say, 'This is the biggest acting job in the world. "Please stop victimizing me through the media". "Did you hear anything I said?"
The Duchess' father has given several interviews portraying the alienation with his actress daughter, who abandoned her Hollywood career to become a Royal. "It's small and she's made it cosy, but the perception of their lifestyle and the reality are two different things". It was our time.
Oftentimes a girl's relationship with her dad is one of the most important in her life. "She made tea every day", the friend said. That's how she plays with them. "How much she loves her animals, how much she loves her friends, how much she loves feeding you, taking care of you - none of that has changed", she said.
