Margaret Loughrey once claimed that she regretted winning the EuroMillions, and believed that she would "never be at peace".
The 56-year-old was tragically found dead on Thursday morning - eight years after scooping a life-changing €31million.
The Tyrone woman was discovered at her home in Strabane - but police have ruled out foul play, and aren't treating her death as suspicious.
Ms Loughrey reportedly lived alone in the Ballycolman area, where emergency services were called at around 10.30am.
A Police Service of Northern Ireland spokesperson said: "Police received a report of the sudden death of a woman at the Ballycolman Lane area of Strabane on Thursday 2nd September.
"A post mortem is due to take place but at this stage, the death is not being treated as suspicious."
Ms Loughrey, who was unemployed, bought her winning ticket on the way home from the Job Centre in 2013.
She said at the time: "I left the house on Tuesday because I heard there was a job advertised and I wanted to apply for it.
"So I went to the job centre and printed out the job application before going to Supervalu.
"I can't always afford to do the Euromillions but I had a couple of extra pound in my purse and just on the spur of the moment I did a Lucky Dip."
But years after scooping £27million (€31m), Ms Loughrey claimed the victory "destroyed" her life.
She claimed she was left with just £5million (€5.8m) in 2019 and that she had been the victim of numerous thefts.
The woman told the Sunday Life: "I will never have peace as long as I live. Even if I didn't have a penny left, I won't.
"I regret winning the lottery. Of course I do. I was a happy person before. I am a human being and all it has done is destroy my life."
At the time of her win, Ms Loughrey was living on benefits of £62 (€72) a week and since the windfall she had been handing out her money to people in need.
She also splashed out €1m to buy the historic Herdman's Mill in Sion Mills and had planned to transform it into a leisure and tourism destination.
Talking about the moment she realised she had won the jackpot, Ms Loughrey said: "I got up at 7am on Wednesday and put on the television. I just had this notion so I checked my numbers and there they were.
"I was just in state of shock and I must have checked 10 times.
"I took a walk out to the back garden and sat out there for a while before coming back in and checking again.
"I must have walked around the house for five hours before ringing my brother and asking him to call up."
Difficulties
In August 2015, she was ordered to do community work for attacking a taxi driver outside her home.
Strabane Magistrates' Court heard she had been drinking vodka and "was highly intoxicated after consuming a large amount of alcohol".
A prosecution lawyer said Loughrey, who had no previous criminal convictions, verbally abused police following her arrest.
