Carmel Kidney, from Ballincollig, has already endured unimaginable heartbreak as a mother who lost three sons to addiction.
Now living alone, she has become the victim of a random rock attack, which has been described as a senseless act of thuggery.
The rock grazed her forehead as she was sitting near the window at the time.
“I do not feel safe in my home and this is not acceptable.
“I cannot sleep with the worry. I don’t know why I was targeted.”
The organisation Support After Crime (SAC) said such random attacks can have life-changing consequences for people, particulary vulnerable people living alone.
SAC founder Sally Hanlon said: “The fact that somebody would recklessly inflict harm on them is terrible. How would the people who are randomly carrying out these offences feel if they were done to their own family?”
Meanwhile, Cork businesswoman Sandra Murphy has also been left feeling terrified in her home on Model Farm Rd after a wave of break-ins in the area.
Gardaí are conducting patrols on the western end of the Model Farm Rd following a spate of thefts from cars in the past month.
