According to People magazine, the 25-year-old singer and her mother, Dianna De La Garza, left Los Angeles and flew to Chicago to meet with a psychiatrist who specializes in mental health and sobriety treatment.
"She's in the midst of recovery," a source told the publication.
"It's going to be a long road, and Demi knows that. Emotionally, it hasn't been easy, but she's doing okay," it added.
Last month, Lovato overdosed on what was reported as an unspecified opioid. She was found unconscious in her Hollywood Hills residence. She was then taken to Cedars-Sinai hospital, where she listed in stable condition and has remained there since the incident.
Earlier this week, the singer cancelled the rest of her 2018 tour dates to focus on her recovery.
In an Instagram post recently, the singer spoke about her battle with addiction, saying she needed "time to heal and focus on my sobriety".
"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," she added.
