Harry wanted men to talk about their problems. Now therapy has been weaponized against him | Sam Wolfson

The duke and his brother have spent years as mental health advocates - and therapy has fueled Harry's public outpouring

While the revelations in Prince Harry's book have shock value, the format they come in does not. The tell-all memoir, ghostwritten with the most salacious stories parcelled into pre-publication interviews, is a media set piece. Subject, publisher and publicists all know their roles and - bar a few early leaks - things have been staged-managed effectively.

But what's so unusual about Harry's revelations is how they have been compared to, and intertwined with, a far less premeditated form of disclosure: therapy.
