Singer Demi Lovato has spoken about her relapse two weeks after she was hospitalised over a drug overdose.

“I have always been transparent about my journey with addiction,” she wrote on Instagram on Monday morning (Sunday US time).

“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.”

The former Disney star thanked God for “keeping me alive and well” as well as her family, friends, fans and the team at Cedars-Sinai Medical Centre, Los Angeles for their support.

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

On Tuesday, July 24 TMZ reported the 25-year-old was taken to a Los Angeles hospital from her home in the Hollywood Hills.

According to NBC , the star was “stable and alert and breathing” after being administered an overdose reversal medication.

Early reports stated Lovato had suffered a heroin overdose, but this has not been confirmed, with suggestions the cause was another narcotic.

The pop star and actress has previously spoken about her substance abuse and addiction issues. Her recent hitSoberfocused on how she broke her six year sobriety from alcohol, cocaine and the prescription drug, Oxycontin.

“Momma, I’m so sorry, I’m not sober anymore / And daddy, please forgive me for the drinks spilled on the floor,” she sang.

“To the ones who never left me / We’ve been down this road before / I’m so sorry, I’m not sober anymore.”

Lovato was last seen performing on stage on Sunday at the 2018 California Mid-State Fair in Paso Robles and was scheduled to perform at Atlantic City in New Jersey in late July.

After news broke, fans of the singer flooded social media with messages of support, with many sharing their personal stories of how Lovato affected their lives.

Demi Lovato has saved my life multiple times and has encouraged me to do better, be better and live better. Nobody has touched my life more than she has. I love you so much @ddlovato.
