Broadcaster Niall Boylan has revealed he had suicidal thoughts after his marriage broke down last year.
The 4FM presenter (53), who has previously spoken about being adopted, said he was in a dark place following the split.
"For about four months, I was so depressed," he told Hot Press magazine.
"There was one night I genuinely felt like there was no way out. I was up on Howth Head, five hours sitting in the car.
"If it wasn't for a good friend of mine on the phone, I don't know what I would've done."
Boylan has since moved on and is in a relationship again, describing the new woman in his life as an "amazing person".
"She's just such a gentle, supportive, affectionate, beautiful and amazing person," he said.
"It was probably the best thing to ever happen to me."
Speaking about his biological mother, Boylan admitted that he believed his birth in a mother and baby home was a result of her being sexually assaulted by a priest.
"My biological mother started saying something about 'a man of the cloth'," he said.
"And I'm going, 'Are you telling me that my father's a priest?'
"She said, 'Can we talk about something else'. I didn't push her because it was upsetting her.
"I would be 100pc sure that she was taken advantage of, probably by a priest."
Outspoken as ever, the popular Dublin presenter did not mince his words when it came to some of his contemporaries on the airwaves.
"Ray D'Arcy. I don't think he's good," he said.
"I don't think he's worth the money RTE are paying him. I'm sure he's a nice guy; I don't know him. I just never rated the guy. I always felt he sounds like he's nervous."
Boylan also had his say on Liveline presenter Joe Duffy, who is one of RTE's highest- paid stars, with earnings of €389,988 in 2015.
"It's not my type of radio. He's basically a referee," he said.
"What's he on for? An hour and a quarter, and he's getting, whatever, €400,000 a year. Don't get me wrong, I wouldn't turn it down.
"But taxpayers' money could be put to better use. We can put together two shows in a day for probably less than a quarter of the price."
Boylan also revealed he had tried drugs, but not cocaine or heroin.
He added that he had not ruled out a career in politics some day and had plans for how he would reform the Dail.
"I don't think people would like me. I wouldn't agree with all the lefties - I'd have to kick them out," he said.
"I'd ban every single one of them from the Dail because they're all mental."
