Joe Tracini's brain sometimes tells him that taking his only life is the "best and only option" he has.
The 30-year-old star started to well up on live TV as he opened up about a recent piece he wrote to highlight World Suicide Prevention Day - which told how he experiences suicidal thoughts which write off "whole days" - and he has urged people who go through dark times to "wait" for happier moments.
He said: "Something I've learnt is life is a stack of moments and you can only ever see one at a time, and sometimes my brain tells me that taking my life is the best and only option I've got.
"I know this happens to a lot of people.
"I think the important thing to tell myself and anybody else is that in that moment you might feel like that and you might feel like that in the next one, but there will always be a moment where you won't feel like that.
"So please wait for it."
The "Hollyoaks" actor - who plays Dennis Savage in the `soap - admitted he will pen a tome about his experiences if anyone wants him to, and he has encouraged people to talk if they are going through any issues.
When it was suggested he should write a book, he said: "If somebody wants me to write a book I'll write a book.
"I feel in a more confident place to be able to deal with what my brain is doing.
"To talk about it I have to talk about it, and luckily I'm in a position where I can talk to lots of people about it.
"Just keep talking about it."
Joe - who wrote a piece for Mental Health Week in May about previously contemplating suicide - was pleased to see a positive response to his recent World Suicide Prevention Day post, which was shared by James Corden, and admitted he only received one negative comment which was directed towards the "Late Late Show" host rather than his own writing.
Speaking on "Lorraine", the star - who is the son of comedian Joe Pasquale - added: "There were thousands of people who got in touch and not one of them had anything bad to say.
"The only negative comment I got was a bloke from Tallahassee who was angry that James wouldn't listen to his Carpool Karaoke idea. I'm fine with that. I'm absolutely good with that."
Last week, Joe wrote about nearly taking his own life six years ago and admitted that while the years have passed "it doesn't mean the thoughts have gone", and that he has an "underlying shame and fear" when he is experiencing "any moment of happiness".
