“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 on Sunday in a message shared on her Instagram account.
“I want to thank God for keeping me alive and well,” she added, before praising her fans for standing by her through this difficult time.
“To my fans, I am forever grateful for all of your love and support throughout this past week and beyond. Your positive thoughts and prayers have helped me navigate through this difficult time,” she remarked.
The post comes just one day after Demi reportedly agreed to enter a treatment facility following her release from hospital, where she remained for 12 days after the overdose due to "complications".
“Demi is well enough to leave the hospital this weekend," a source told People. "She has agreed to rehab and will go straight to an in-patient facility.
“She wants to be sober. She wants to get help. She understands that it will take a lot of work and commitment to stay healthy, but this is what she wants.”
