The 25-year-old broke her silence on Sunday with a lengthy Instagram post, saying she remains committed to overcoming addiction.

"I have always been transparent about my journey with addiction. 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 wrote. "I now need time to heal and focus on my sobriety and road to recovery. 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."

Lovato thanked God, her fans, family, team and hospital staff in the post. She closed with: "I will keep fighting."
