At least 20 survivors and witness of the Grenfell Tower fire have attempted suicide, a charity has said.

Silence of Suicide founder Yvette Greenway told the BBC’s Victoria Derbyshire programme the number was based on conversations with those supporting residents.

Justice4Grenfell’s Judy Bolton also said volunteers working with survivors had told her of 20 suicide attempts.

The BBC has been unable to independently corroborate the figure.

Chelsea and Kensington Council has not been able to responded to a request for comment.

‘Alcohol dependency’

Ms Greenway said many occupants were unable to get images of the burning tower “out of their minds”.

“There is a lot of booze and drug dependency, ” she said. “People are seeming isolated.”

Ms Greenway said there was little confidence in “council-led” mental health services.

“We’ve been told workers are going around putting leaflets under hotel entrances and not actually speaking to people, ” she said.

“There are going to be many more instances of PTSD[ post-traumatic stress ailment ], depression, anxiety and self-harming as people reach different stages of trauma.

“Everybody will be affected at different times.

“We need long-term mental health provision for the next three decades at the least – maybe longer.”

Survivor guilt

Ms Bolton, a nurse for 20 times who is now co-ordinating volunteers for Justice4Grenfell, said mental health support services needed to be rethought.

She said rather than waiting for survivors to actively seek help, services should instead “go to them”.

Ms Bolton proposed there were multiple factors in why people were attempting suicide, including depression, survivor guilt and thought unable to cope with the loss of loved ones.

“There only isn’t the proper psychiatric help that people need, ” she said.

“They necessity traumata and bereavement attorney urgently.

“People are self-medicating to shut out the trauma.

“We were inundated with drug dealers praying on the traumatised.

“People appreciated their neighbours falling from a burning house.

“They considered children being plummeted from the building.

“There are still ashes still blowing over us when the train runs past.

“We’re being covered in the ash of our dead friends and relatives.”
