While Lauren has recovered from her eating disorder, she has admitted that she's still seeking help for her issues - the real wakeup call came when doctors warned her it could be bulimia or her career.“They told me that if I didn’t stop, I would never sing again, and I didn’t want that,” she told ET: “That was a wake-up call for me, and it took me a few years even after that to really get into a better place. And I still go check in with the therapist every once in a while, specifically for an eating disorder.”Happier And HealthierBack in 2017, and reflecting on being 20 pounds lighter as a result of her destructive behaviors, Lauren opened up to Self, telling the magazine she didn't regret getting healthier - and heavier."I used to eat food out of anger and sadness and emotions, and now I eat food because I’m hungry and I need food—food is fuel," she said. "I think I look way better now than I ever did when I had an eating disorder, and I was smaller then. I was 20 pounds smaller. But I’m healthy now and this is where I should be."
