IN HER complaint to the HCCC, Brooke Bowen says she believes her father, Danny Bowen, would still be alive today if he had only been given the help he asked for.
"The man with great strength and honour had the courage to reach out and he was turned away," she wrote.
"Now my mother and brother have to live (with) the fact they found him and tried to revive him. That stays with them as a memory they should never have to live with.
"My sister and myself will never have our father walk us down the aisle to get married (and) our kids, his eight grandchildren, will never be able to get to know their grandfather who loved them so much."
Ms Bowen said the hospital learnt nothing from the tragic handling of her father's case because two weeks later, her partner, Adrian Warrick, experienced similar treatment.
Mr Warrick had a history of mental illness which included a one month stay at the Lismore Mental Health Unit due to trauma stemming from the 2011 murder of his two-year-old daughter, Tanilla Warrick-Deaves, at the hands of her stepfather.
"After my father took his own life, Adrian said he wasn't coping and asked to be taken to mental health," Ms Bowen wrote in her HCCC complaint.
"He told them he wasn't coping and wanted help (and) he was told to go see his local doctor and get a mental health plan.
"Just a week and a half I think it was later Adrian tried to hang himself jumping off the back deck. I had to hold him up while calling ambulance and police. He attempted three times during this time. Ambulance and police took him to hospital… (and) within three hours he was allowed to come home.
"Now these are only two people and I have met a lot along our journey of grief that have been turned away by Lismore Mental Health and ED.
"I understand we are all human but how many errors need to cost people their loves when they are employed to help people?"
