In addition, her husband was admitted to London’s King Edward VII’s Hospital a week ago after feeling ill. Buckingham Palace shared that the 99-year-old is being treated for an infection and is not expected to leave the hospital for several days.
During England’s current lockdown, he and the queen had been staying at Windsor Castle, west of London.
"It’s been a rough few weeks for the queen, that’s for sure," a royal source told on Wednesday. "The situation with Harry and Meghan has been challenging, and on top of that, she’s distraught over her beloved husband’s health setback."
Philip married the then-Princess Elizabeth in 1947 and is the longest-serving royal consort in British history. He and the queen have four children, eight grandchildren and nine great-grandchildren.
"The queen has had some tearful moments mixed with anger and disappointment," another palace insider alleged to the outlet. "Emotions are definitely running high."

Harry, who served in the British army for a decade and has a close bond with the military, founded the Invictus Games competition for wounded troops.
The decision came one year after Markle and Harry announced their plan to step back as senior members of the royal family. At the time, they agreed to a 12-month review of the decision.
It was made after the pair held conversations with members of the royal family.
In response, a spokesperson for the couple said in a statement that "as evidenced by their work over the past year, The Duke and Duchess of Sussex remain committed to their duty and service to the U.K. and around the world, and have offered their continued support to the organizations they have represented regardless of official role. We can all live a life of service. Service is universal."

At the time, the Duke and Duchess of Sussex said their decision came "after many months of reflection and internal discussions."
As for Philip, his youngest son told Sky News that the patriarch was "a lot better."
The 56-year-old said, "he’s looking forward to getting out, which is the most positive thing, so we keep our fingers crossed."
Other members of the royal family have continued their official duties during Philip’s hospitalization.
Philip, also known as the Duke of Edinburgh, retired from public duties in 2017 and rarely appears in public.
Both Philip and Elizabeth, 94, received vaccinations in January.
