Demi Lovato is doing "great" after entering rehab in 2010 to seek treatment for drug and alcohol addiction, depression, bipolar disorder, and anorexia and bulima.
Lovato said she still has her share of bad days, but she's a lot better at dealing with negative emotions than she used to.
"Since I went to treatment, there have been days when it's felt really easy, and I've felt great about where I am," Demi told Seventeen. "But then I have moments when it's not. That's life. You can't just take your mind and your body into the shop and get it fixed. It doesn't come out repaired. It's not like a car."
Lovato, 21, treats her bipolar disorder with medication and therapy. "That's what works for me — medicating, checking in with people, being honest and being grateful for things," Demi said.
While she still struggles with depression and dark thoughts, Lovato said making a concerted effort to actively focus on the positives in her life on a daily basis has helped her cope with negative thoughts.
Lovato, who was addicted to alcohol, cocaine and pot, confessed that she used to smuggle cocaine on airplanes to feed her dangerous addiction.
Demi also suffered from the eating disorders anorexia and bulimia since the age of eight, and at one point starved herself down to 88 pounds. She finally ended the vicious cycle of bingeing and purging after realizing she could kill herself from the disease.
"I started compulsively overeating," she said. "I would bake cookies and then eat the whole pan. I went to just starving myself, and that turned into throwing up and starving myself. I would throw up and it would just be blood. I realized if I don’t stop this, I am going to die.”
Demi said her rock-bottom moment came when she was sitting at an airport at nine o'clock in the morning with a bottle of Sprite filled with vodka. She threw up in the car that had been sent to take her to a sober living facility and realized she needed to clean up her act.
Interestingly, Lovato's mom Dianna revealed that she suffered from eating disorders and depression, and blamed herself for Demi's problems. Fortunately, the problems have brought Lovato and her family closer together.
Lovato said she wants to be a role model for other young girls suffering from similar problems. Looking back, she's glad she went public with her problems because her experiences may be able to help others. Lovato, who's currently on her world tour in support of her hit album Demi, is happy with her progress and has big dreams for her future.
"I've done that a lot over the past few years, but it has been so worth it, because the people in my life today inspire me to keep being creative, to have fun, and to be a good person," she said.
Demi detailed her harrowing battles with drug addiction, anorexia and bulimia in her bestselling book, Staying Strong: 365 Days a Year.
