Sweetman denied reports that her relationship with her daughter immediately before her death was strained. She told People, "There's a story that has been published saying that I sent Cathriona an email on her birthday nine days before she died, calling her a failure. I don't know who would say such lies, but this is something that never, ever happened. I am devastated people would say this."
Brigid's life has been threatened by people who believed that story, and who felt her words pushed Cathriona to suicide. She revealed, "It has made my grief 100 times worse, if that could be possible. And that's why I am putting the record straight here. I feel I have to speak out now because I am in fear in my own house. Basically, the way it is here now, I am scared to go out of the door. I would love to move out of this house, but I can't afford it."
She added, "I absolutely adored Cathriona, like I adore all my three children. They are my life and I'm so proud of all of them. From the moment she was born, I cherished her. Calling her a failure is never something I would ever have done. It's an awful thing to say to anyone, let alone your own child."
"Yes, we had had an argument. But what family doesn't argue at some time? It was over nothing and it would have been resolved. It's just hard when your daughter is on the other side of the Atlantic, you can't put your arms around her," Sweetman continued.
Sweetman has coped with her sadness by visiting White's grave in Ireland and leaving flowers and notes. She recently left a note, saying, "If I could hold her just once again, I would never let her go."
Cathriona's body was found at her Los Angeles home in September with pills and suicide notes by her side. The official cause of death has not been determined.
