When 18-year-old Stacey Goodwin got a job at a bookies, she put a pound coin into a slot machine and won enough money for a night out with her pals. It was the trigger for a destructive gambling addiction that led to a life of shame, brutal isolation and deceit. The money she lost over an eight-year period was eye-watering – on one occasion, frittering away a £50,000 online win in a matter of days. Sometimes suicidal, and always lonely, it was the damage she did to those closest to her which hurt the most.When her addiction saw her undermine the financial security of someone she loved, she reached a crossroads. Stacey tells Dr Sian Williams how she found the strength to ask for help - and turned her life around. Producer: Tom AlbanWarning: This episode contains discussions around suicide.
