This kind of slipped through the news on Monday, but Avril Lavigne announced she’s going on tour this late summer/early fall.

Seriously, she’s doing a month-long, 15 city tour starting September 14th in Seattle and winding through the U.S. with a stop in Detroit at Fox Theatre on September 28th.

The tour, Avril’s first in five and a half years, is named after a prayer she said to God, while she was battling Lyme disease and was stuck in bed, she told Billboard Magazine.

“I had accepted that I was dying,” she says. “And I felt in that moment like I was underwater and drowning, and I was trying to come up to gasp for air. And literally under my breath, I was like, ‘God, help me keep my head above the water.’ ”

Even as she lay there, thinking she was dying, she pulled out her phone and made a note, which later became a song, and then a tour, according to Billboard.

She has since started the Avril Lavigne Foundation, which aims to “lead and inspire a community including, fans, friends, families, advocates, and partners who can come together to provide unity and support for those in need.

I tell you all that, because after her announcement, she posted a separate Instagram post explaining that proceeds from the tour will go to the foundation,

Excited to announce that a portion of the proceeds from every ticket sold on my “Head Above Water” Tour will be donated to The Avril Lavigne Foundation to raise awareness & fund treatment for those in need!
