Markle has reportedly been video chatting with her close friends and exchanging cooking recipes.
Last week the pair released a statement saying social distancing was “a lot to take in”.
“Our emotional well-being is challenged every day whether we realise it or not, but our lives are usually filled with distractions,” the couple said on Instagram last week.
“Now with constantly changing COVID coverage, we are all adjusting to this new normal and the feelings that come with it.
“These are uncertain times. And now, more than ever, we need each other. We need each other for truth, for support, and to feel less alone during a time that can honestly feel quite scary,” the statement continued.
Per People, Harry has also been in touch with his father, Prince Charles.
The diagnosis reportedly brought Harry closer to his older brother, Prince William, after ongoing reports of a feud.
“Harry and (his older brother) William are now on speaking terms again and this has healed the rift that was ongoing,” a palace insider told UK media correspondent Neil Sean.
“Both brothers have linked with Charles via video and joked and made him feel happy that they were together again.”
It comes as US Weekly reports Markle plans to write another cookbook, her follow-up effort to her 2018 release Together: Our Community Cookbook for charity.
A source told the outlet that additionally, the Duchess of Sussex is looking to relaunch her former lifestyle blog The Tig, as well as developing a kitchenware line.
“Meghan has heaps of projects in the works,” the insider told the magazine.
This week it was reported Markle had landed her first post-royal job since stepping back as a senior member of the royal family in the form of a voiceover job for Elephant, an upcoming Disney+ documentary to be narrated by Markle.
And on Friday it was revealed the Sussexes had relocated from Vancouver Island in Canada to Los Angeles, according to People.
It is unclear when exactly the couple made the move.
Back in January, Markle and Harry announced that they would take “a step back” as senior members of the royal family and instead work independently, splitting their time between the United Kingdom and North America.
