Sir Bob Geldof has revealed he "half-expected" the death of his daughter Peaches.
In an emotional interview, the singer and campaigner spoke of the impact of the deaths of three women in his life - his mother, his former wife Paula Yates and his 25-year-old child.
"It's different, I mean, part of me kind of half expected Peaches, to be honest with you," he said.
"The way she was carrying on, there is nothing you can do about it, but she is the one who is with me every second of the day and she's the one who bounds into my consciousness at any moment, especially in any down moment. I don't mean any depressing moment I mean when I am not doing something."
Sir Bob added: "This thing of being forever 25, in my head, that's unbearable simply because of that cliche you're not sup posed to see your children die.
"The rest in context is alright."
The Boomtown Rats frontman said he felt lucky that he had music to help deal with grief and spoke of the catharsis of performing on stage and the prospect of writing a song about Peaches.
"It will out. I'm a lucky man. I get to realise these things in songs," he said.
"I feel afterwards light, literally light. My head is clear, there is no ache, there's no gut sadness,"
Sir Bob spoke openly about the losses in his life in an interview on Sunday with Miriam on Ireland's state broadcaster, RTE Radio.
His daughter Peaches, a mother of two, journalist, model and television presenter was found dead in her home in Kent in April last year. A post mortem discovered heroin in her system.
Sir Bob spoke of the different feelings he had following his daughter's death and the death of his late wife Paula Yates from a heroin overdose in 2000 aged 41.
"The leaving was worse than the dying," he said.
"I couldn't understand it. I loved her profoundly. I didn't understand it then that love is not enough."
Sir Bob recalled being phoned with the news of his former wife's death on a Saturday morning when he was holding a breakfast birthday party for his daughter Pixie.
His mother Evelyn died when he was seven.
In a television interview last year Sir Bob said he "blames himself" for his daughter's death.
