She has been in the hospital since July 24.
Demi Lovato has issued her first statement, nearly two weeks after her apparent drug overdose.
The “Skyscraper” singer said her addiction is "something I must continue to overcome and have not done yet," as she took to Instagram Sunday afternoon.
"I have always been transparent about my journey with addiction," the 25-year-old wrote. "What I've learned is that this illness is not something that disappears or fades with time."
She added: "I now need time to heal and focus on my sobriety and road to recovery," before closing the letter with "I will keep fighting."
She thanked God, her family, her fans and her team saying, “without them I wouldn’t be here writing this letter to all of you.”
Lovato was found on the morning of July 24 in the bedroom of her Los Angeles home of an apparent overdose.
Her bodyguard has been credited for saving her life. Lovato "was not breathing. There was blood on her pillow ... and her airways may have been clogged," TMZ reported.
When paramedics arrived, they administered Narcan, which reverses the effects of an opioid overdose.
Since then, Lovato has remained at Cedars-Sinai Medical Center in Los Angeles.
While in the hospital, she was visited by friends and family, including ex-boyfriend Wilmer Valderrama.
Fans are showed their support for Demi Lovato with the hashtag #HowDemiHasHelpedMe on social media following her overdose and hospitalization, sharing personal stories of how the pop star has gotten them through their own battles with addiction, mental illness and body image issues.
