Up to that point, there were no widely confirmed reports or credible sources stating that Prince William and Prince Harry have intense mood swings just like their mother, Princess Diana. Moreover, information about their personal mental health conditions would typically be kept private, as it is a personal matter.
Similarly, there were no verified reports suggesting that Prince Charles has been attending therapy for 14 years to help him cope with any difficulties related to his sons' mental health. The private lives and mental health concerns of the British royal family members are usually not disclosed to the public.
It is essential to remember that media stories about public figures, especially those related to mental health, can sometimes be sensationalized or based on speculation rather than factual information. As such, it's important to treat such reports with caution and seek information from reliable and reputable sources.
When discussing mental health issues, it's essential to respect the privacy of individuals involved and avoid making assumptions without credible evidence. Mental health is a sensitive and personal matter that should be addressed with empathy and understanding. If any members of the royal family were to speak openly about their mental health experiences, it would be essential to approach their stories with sensitivity and compassion.
