Nearly two weeks after being hospitalized at Cedars Sinai Medical Center in LA due to a reported overdose, Demi Lovato has broken her silence in an Instagram message to fans, in which she promises she’ll “keep fighting.”

“I have always been transparent about my journey with addiction,” the 25-year-old singer wrote. “What I’ve learned is that this illness is not something that disappears or fades with time. It is something I must continue to overcome and have not done yet.”

She went on to tell fans that she’s “forever grateful” for all of their “love and support throughout this past week and beyond,” and that their “positive thoughts and prayers” have helped her navigate this difficult time.

She also thanked her family, her team, and the staff at Cedars-Sinai. “Without them I wouldn’t be here writing this letter to all of you,” she shared.

“I now need time to heal and focus on my sobriety and road to recovery,” she continued, addressing what’s to come. “The love you have all shown me will never be forgotten and I look forward to the day where I can say I came out on the other side. I will keep fighting.”

Lovato, who has reportedly battled extreme nausea and high fever while in the hospital, is expected to be released soon. E! News reported earlier this week that she will then head to rehab to continue her recovery.
