Bob Geldof contemplated suicide following daughter Peaches' death.
The Boomtown Rats frontman was left devastated in April, 2014 when 25-year-old socialite Peaches was found dead at her home in Kent, England after suffering a heroin overdose.
In a new interview, Bob, 64, has revealed the tragic passing of his little girl led to him even considering taking his own life.
"I’d make lists and keep working at the writing of those lists until the upside overwhelmed the downside," he told Britain's The Sun newspaper.
“In my case I wrote: ‘What’s the upside of being alive?’ and ‘What’s the downside of it?’. Was it ever really serious? Overall, no. In that moment though, perhaps it was."
Luckily, Bob contacted a friend in his darkest times, and was talked out of doing anything rash.
"I had the sanity, luckily, to phone a friend and tell him, ‘Look I think I’m just starting to get irrational’," Bob added. "He almost slapped my face (with his tone) and said ‘Don’t do anything f***ing stupid, stay exactly where you are’ and came around very quickly."
Following Peaches' death, it emerged the mother of two had been receiving professional help for her addiction issues for two-and-a-half years before her death, and had been taking drug substitute methadone as part of her treatment programme to wean her off heroin following her relapse.
Her passing was strikingly similar to the death of her mother Paula Yates in 2000.
Live Aid hero Bob previously revealed her drug troubles led him to believe she would pass away before her time.
"Part of me kind of half-expected (it with) Peaches, to be honest with you," he told RTE Radio 1 presenter Miriam O'Callaghan. "The way she was carrying on, there's nothing you can do about it."
