Loose Women panellist June Sarpong has paid tribute to her brother Sam who died after jumping from a bridge.
She returned to the ITV show on Thursday morning alongside Andrea McLean, Linda Robson and Jane Moore and spoke for the first time about his death in October 2015.
She said: "It's horrible, I wouldn't wish this on anyone. I mean it's been such a tough time for my family and I. 2015 was the worst year of our lives, like the worst, nobody could ever have predicted this."
Sarpong, 38, spoke about the lack of warning signs and called for viewers to help end the stigma of depression.
She said: "He'd given no signs, this is the person that you would never associate this with, I mean the last.
"In a world full of seven billion people, I feel so blessed to be able to say that my favourite person in the world was my brother. I mean he was so good.
"He was such a kind human being who just loved people and who treated everybody the same and was the life and soul of the party and whenever you had a problem, he was the guy you turn to...
"The thing that really sort of brought it home to us, just how loved he was, was at his memorial, over 2,000 people turned up to celebrate his life."
Sam, 40, died after jumping off a bridge in the US.
He had modelled for Tommy Hilfiger and acted in television series Bones.
The TV presenter said: "He wasn't on medication, he doesn't even drink. All we know that on the day it happened, something just took over his mind.
"So the Sammy that we knew was not that boy on the bridge, the person that jumped off the bridge was not the man that we had loved for over 40 years. It was a moment of mad... something just went off and he lost complete control over his mind..."
Addressing people who might be suffering like her brother, Sarpong said: "For anybody even considering it, even having those thoughts, I beg you on behalf of the people you love, on behalf of your family, your family, the teacher whose favourite student you were, don't do it.
"Because that pain doesn't go, that pain gets dumped on the people you love. Whereas if you seek help you can get over it and as long as you're alive there's always hope."
