She had gotten up to use the bathroom when she inexplicably experienced giddiness and blurred vision. That same day, she was admitted to the Accident & Emergency department unconscious.
Tragically, the doctors have now told her loved ones to prepare for the worst.
The abrupt and shocking turn of events has left her family — including Mediacorp actor Benjamin Tan, her only child — lost and heartbroken.
In an interview with 8 Days, Benjamin said his mum is relying on life support machines to help her breathe.
When she was admitted, the doctors told him that she had developed a blood clot which is pressing against her brain stem.
Although her condition improved after three days in the Intensive Care Unit, she later experienced a severe headache and fell into a coma. After doctors discovered internal bleeding in her brain, they told Benjamin and his father to prepare for the worst as she "could go anytime".
The 27-year-old actor, who starred in the recent Chinese drama My Guardian Angels, said: "Of course, my dad and I would love to see my mum back to her normal self, but I also understand that sometimes letting her go might be the better option for her. That's the internal struggle that I've been trying to overcome for the past week."
He added: "I do not want to lose my mum now, especially when she's only 52. I've yet to repay her for bringing me up all these years."
Although Benjamin just started work on a new Mediacorp drama, the producers and crew have been very understanding, and he has been able to spend time by his mother's side.
"Every day is a struggle for me. Whenever I sit by her bedside, I can't help but cry. I'm trying to find ways to distract myself but it's really tough," he said.
