The Royal Court confirmed to the Aftonbladet daily that the break up from Bergström is the reason why Madeleine cancelled her attendance at Sweden Week in Seattle at the weekend, having to be replaced by her sister Crown Princess Victoria.
"She needs personal time and peace and quiet. Madeleine is not feeling too good," Nina Eldh at the Royal Court told the newspaper.
The court confirmed that the princess has cancelled all engagements up to May 30th, the date for the publication of the marriage banns for Victoria and Daniel Westling.
Madeleine travelled to the USA at the end of April to fulfil a series of engagements and to escape the media glare after revelations over Bergström's alleged dalliance with a Norwegian handball player.
Calls from the palace to leave the Princess in peace as she adjusts to life without her erstwhile fiancé fell on deaf ears however as Scandinavian news teams were joined at Newark Airport by international paparazzi photographers.
But the Princess succeeded in leaving the airport undetected by reporters and photographers after the well-documented turbulence in her relationship with Jonas Bergström culminated in the April 24th announcement that the couple had chosen to go their separate ways.
Princess Madeleine's engagement book was scheduled to keep her in the United States until May 9th, with a lengthy spell at the World Childhood Foundation, an organization founded by her mother Queen Silvia ending with the trip to Seattle.
