“I now need time to heal and focus on my sobriety and road to recovery,” she wrote. “I will keep fighting.”
Lovato has long been open about her struggles with sobriety, an eating disorder and being bipolar. She said she first tried cocaine as a teenage Disney star.
She discussed staying at a sober living house with the media.
In June, she shared she had relapsed and released a song called “Sober.”
A source close to Lovato previously told CNN that Lovato would seek drug abuse treatment following her hospitalization.
