On February 5, Lavigne wrote about the song:
"This is one of the first songs I wrote for the album after Head Above Water. They are both about the health battle I continue to fight every day. I hope my songs can help you find strength if you need it...
I produced this track, Chris Baseford engineered, Chad and Travis Clark helped me finish it. I had a lot of great people around me helping me to make music again".
