Mr Dymond died of an overdose and heart problem at his home in Portsmouth, a previous inquest was told.
Claire Overman represented Mr Dymond’s brother, Leslie Dymond, and son, Carl Woolley, at the preliminary hearing in Winchester.
Leslie Dymond said his brother had told him the audience had “booed and hissed” at him, she said.
Ms Overman said his brother’s account also suggested Mr Kyle had called him a “traitor and a failure” but video evidence showed that the host had not said this, but had called him a “serial liar”.
She added that Mr Dymond had told his brother he was in tears and on the “point of collapsing, incredibly stressed, completely broken” and “consumed by what happened on the show”.
He had talked about considering “jumping out of the taxi on the way home”, the inquest heard.
Ms Overman said his brother also said it was “like he had been brainwashed, he [Steve Dymond] said he was worthless and couldn’t go on living”.
The coroner, Mr Pegg, said Leslie Dymond had been ruled medically unfit to attend the full inquest.
He said that he would accept his written statement as evidence but then make a decision on its reliability.
