Billie Piper has said finding fame as a teenager and living independently from a young age made her "cynical" and "jaded".
The 38-year-old rose to fame as a singer and moved away from home before the age of 18 because of her career.
Piper, who released her debut single Because We Want To aged just 15, revealed on the Changes With Annie Macmanus podcast that she was on "the most punishing schedule ever".
“I think I saw a lot of things at a very young age, and I think some of that can be really good and informative and it means you see parts of life that you wouldn’t normally see, maybe ever,” she said.

“Then in other ways, I would say it made me quite cynical, quite jaded and very reclusive and incredibly paranoid.
“These are the sort of negative changes and things that arguably sort of affected my personality for the rest of my life… things that I’ve tried to deal with since.”
Piper added that by the time she became an adult she was “so angry and so exhausted and burnt out”.
She married Chris Evans in 2001 when she was 18 and he was 35, before they split in 2004.
The singer turned actor said the DJ "knew how important it was" for her to have "some semblance of normal life".
Piper reflected on the marriage to Evans last year, describing it as "so much fun" as they "got completely hammered for three years".
She tied the knot with actor Laurence Fox in 2007 and they welcomed sons Winston, 12, and Eugene, eight, before splitting in 2016.
She is currently in a relationship with Tribes frontman Johnny Lloyd. The pair welcomed their first child, daughter Tallulah, in January 2019.
