Sir Bob Geldof is still recovering from Peaches Geldof‘s sudden death in April.

“She was super bright, too bright,” said Sir Bob, 63, to ITV News on Wednesday about his late daughter, who died of a heroin overdose at 25. “She knew what life was supposed to be. God bless her she tried, very hard to get there. And she didn’t make it.”

He says he blames himself for his daughter’s death. “I’m not just blaming the newspapers, of course not,” he continued. “You blame yourself. You’re the father who’s responsible and clearly failed.”

The Live Aid founder often thinks he could have done more to save Peaches’ life. “For anybody watching, who has a dead kid and you’re a parent, you go back, you go back, you go back, you go back, you go back, you go over, you go over, what could you have done,” he said.

Even months after her passing, he’s still grieving and struggling to find answers.

“The ability to try and understand, though it isn’t comprehensible, or try to come to terms with the immensity of the grief is there,” he explained. “But it takes a long while to filter through. I’m not there yet with Peaches. It was all too soon. Too sudden. Too unexpected.”

Despite the tragedy the year has brought him, Sir Bob finds some relief when he takes the stage. “It is utterly cathartic those two hours. I am drained. It drains my mind,” he said. “It’s very useful.”

Peaches’ mother, Paula Yates, also died of a heroin overdose in 2000. Peaches is survived by her husband Thomas Cohen and two sons.
