Avril Lavigne has released her first song in five years following a battle with Lyme disease.
The Canadian singer released Head Above Water on Wednesday, which details her struggle with the debilitating illness.
Lavigne, 33, revealed the song was written on a bed "during one of the scariest moments of my life. I had accepted death and could feel my body shutting down".
Earlier this month, Lavigne posted an emotional open letter on her website detailing her battle with Lyme disease, which has a range of symptoms and can leave the victim exhausted.
'Worst years of my life'
Lavigne said she has endured the "worst years of my life" and has been through "both physical and emotional battles".
The disease is a bacterial infection that can be spread to humans by infected ticks. It's easier to treat if diagnosed early, but can still result in tiredness, aches and loss of energy that lasts for years.
Former Rugby star and TV presenter, Matt Dawson, underwent heart surgery after contracting Lyme disease in 2016.
He told the BBC: "It was a really scary time for me and my family. Such a tiny creature caused me to end up needing heart surgery."
