Demi Lovato on Sunday posted a message to fans just weeks after she was hospitalized for an apparent drug overdose to be “transparent about my journey with addiction.”

“What I’ve learned is that this illness is not something that disappears or fades with time,” she wrote on her Instagram account. “It is something I must continue to overcome and have not yet done.”

The 25-year-old music star thanked God for keeping her alive and thanked fans for their “love and support.” “Your positive thoughts and prayers have helped me navigate through this difficult time,” she said.

She also thanked the staff at Los Angeles’ Cedars-Sinai Hospital, where she received treatment after she was found unconscious in her Hollywood Hills home on July 24 after an overdose.

“Without them I wouldn’t be here writing this letter to all of you,” Lovato wrote.

“I now need time to heal and focus on my sobriety and road to recovery,” she said. “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.”
