Kate Middleton sister's tearful message to brother James at difficult time

Kate Middleton's brother James Middleton has shared heartbreaking details about their family's nightmare.

Pippa Middleton, sister of Princess Kate, left her brother a tearful voice mail message after fearing he had gone away to die, according to James' new book.

In his new book titled "Meet Ella: The Dog Who Saved My Life", James openned up on his battle with depression and a pivotal trip to the Lake District with his dog.

"We set out, the dogs and I, on our southbound journey and I know the exact spot where the mobile phone signal comes back. The pings come thick and fast. 'Where are you, James?' 'We're ­desperate to get hold of you.' 'OK, we're really worried now.' wrote William's brother-in-law.

"My family thought I had gone away to die, to end my own life. I realise that now. I feel full of regret for not recognising just how ­panicked I'd made them."

 He went on: "At the time, however, irrationally – and unjustifiably – I feel annoyed, controlled. I'm a grown man. It has been the most formative trip of my life.

"I had not gone away to end my life. I'd gone to find a reason to live. And I'd discovered it. So why was ­everyone intruding?"

Kate's younger brother continued: "I picked up a voicemail from Pippa: 'James, we're all so worried about you. Where on earth are you?' Her voice was tearful with concern, with just an edge of reprimand."
