Speaking to Vulture ahead of the release of her new album next month, the 33-year-old proved nothing was off-limits during her conversation with the publication.
The Not Fair singer confessed she’d been through a bit of a tough time in recent years.
“I lost my sense of self. I lost my identity. I was being a bad mum. I was being bad at my job. I’d wake up on a tour bus in the middle of Wisconsin and be so hung-over. I cheated on my husband. All I wanted to do was be with my kids. I wasn’t even making any money,” she said.
Lily then went on to say this rough patch ended up costing her a lot of the things she held dear.
“I lost my marriage, I lost my house, I lost my mind. I literally had to hit rock bottom and build myself back up. Then I had my stalker,” she admitted.
“I couldn’t have been more isolated. I lost all of my friends. I couldn’t talk to anybody. I was on my own.”
And while she takes responsibility for the failure of her five-year marriage, Lily said her 40-year-old ex “could have done [more] to protect me”.
Instead, Lily confessed she would often turn to drugs and alcohol for help, saying she has a tendency to self-medicate when things get hard.
“If I’m feeling at my wits end, I’ll reach for whatever’s around me: alcohol, sex, drugs, Twitter,” she said.
“I need boundaries. I need to not let the tabloids knock me for six when they say something horrible.”
While she still enjoys the occasional drink, Lily said she doesn’t use drugs anymore.
She admitted her drug use has previously caused trouble for her, ultimately getting the British pop star temporarily banned from working in the United States.
