Demi Lovato reflected on her newfound sobriety and health in a series of introspective New Year's Eve tweets she sent to her 11.2 million Twitter followers.
"Two years ago, I watched the [New Year's] ball drop on TV in rehab and cried my eyes out," Lovato tweeted. "Tonight I'm on the beach with my closest, most loyal friends, sipping coffee and sharing how beautiful life is and how far we've come. Recovery is a beautiful thing."
While Demi is only 20 years old, she has endured a lifetime of troubles during the past few years. Lovato checked into rehab for drug addiction, bulimia, bipolar disorder and self-mutilation in October 2010 after suffering a series of breakdowns.
Lovato, who once abused cocaine and alcohol and partied all night, became bulimic at age 12 and cut her wrists at the height of her self-destructive period. Demi, who was diagnosed with bipolar disorder, began binging and purging after being bullied and called fat at school.
"They called me a whore and told me I was fat and ugly," Lovato recounted. "I shouldn't have listened, but I took it to heart and it hurt. I thought maybe I didn't have friends because I was too fat."
Demi's bulimia got so bad the 5-foot-2 singer once dropped to a sickly 88 pounds. "I'd make myself sick up to six times a day," said Lovato. "My mom was worried, but because I was going through puberty I was having growth spurts so she assumed that was why I was thinner."
Lovato, who underwent intense therapy during her three-month stint in rehab, now shrugs off negativity.
"Mean comments don't affect me the same way because I'm more confident," she said. "If I read something where someone calls me a b*tch, I know I'm not, so I laugh at it."
