Avril Lavigne has revealed she'd "accepted death" when writing her newest single from her sickbed "during one of the scariest moments" of her life.
The 33-year-old singer contracted Lyme disease, which is spread by infected ticks, in 2014.
"I have decided to be truthful about my struggle, open and more vulnerable than ever before," she writes.
Symptoms of Lyme disease include tiredness and headaches.
It's the most common tick-borne infectious disease in the UK, Europe and North America, and the flu-like symptoms can affect some people for years.
