Jeff Brazier was left heartbroken after his sons told him they wished he had died instead of their mother, Jade Goody.
The former "Big Brother" star tragically passed away in 2009 at the age of just 27 after losing her battle with cervical cancer and Jeff - with whom she had two sons Bobby, 13, and Freddie, 12 - has opened up about the difficulties of life without her.
He told The Sun: "The worst possible thing I've heard from both boys would be: "I wish it was you that was dead and not Mum."
"Grief generates the worst possible feelings, it really clouds your judgement.
"The words they come out with they're not always in control of and they're just saying them because what they're actually trying to say is "Dad, help me"."
Jeff has written a book, "The Grief Survival Guide: How to Navigate Loss and All That Comes With It", to help others deal with loss and it will be released in June.
Jade is never far from Jeff and his sons" thoughts and he previously revealed that they have a "mummy day" once a month in memory of Jade.
The professional life coach - who split from Jade in 2004 - said: "On the 15th of each month that's "mummy day". We can talk about her obviously at any time and we do, but the 15th of the month means we are particularly focused on it.
"We will release balloons or we'll write letters and post them, whether they think they are going to get there or not it doesn't matter, it's expressing. It's writing those memories down, those thoughts and those feelings and even if it's sad and something that you perceive as being negative, it's not hurting them. It's hurting them more not to talk about it than it is to actually put it down on paper and do something with it."
