Avril Lavigne Opens Up About Battling Lyme Disease, Releases New Song ''Fly'' to Support Special Olympics

Singer recently revealed her diagnosis

Avril Lavigne is determined to send a strong, inspirational message to her legions of fans around the globe.

The singer debuted her latest track, "Fly," during a guest appearance on Good Morning America  today and announced that all of the net proceeds will go to the Special Olympics.

"I wanted the athletes to be the stars of the video and, just like the message of the song, to show the world that they can overcome the challenges and that everyone is meant to shine," she shared.

The 30-year-old also opened up about her battle with Lyme disease, saying, "I believe that I will come out of this healthier and stronger than I was before…I've gained a lot of perspective on my life."

Lavigne explained that she first began feeling sick while on tour last spring, but that doctors couldn't pinpoint what was wrong with the Canadian singer for months on end.

"I went from doctor to doctor for about eight months until I found somebody that had the knowledge of Lyme disease and the experience of treating it. I actually knew I had it the whole time, probably since the summer, and was just up against a lot of doctors telling me, 'You're crazy.'"

And while the singer was bedridden for five months, her time at home became the perfect environment to create, and focus on, new music.

"I've never had so much down time in my life, so it's been good in that sense," she shared before discussing her new single.

"It's just about inner strength and courage. This song took on a whole new meaning for me while I was sick, which was pretty magical."
