Looking happy and healthy on the red carpet at the 25th Annual Race to Erase MS Gala, Avril Lavigne says she’s ready to move on after being diagnosed with Lyme disease back in 2013.

“When I was so sick and lifeless in bed I was like, ‘is it over?’ and when I started feeling better and having good days I legit grabbed my guitar and wrote a song called ‘Warrior’,” she tells ET Canada. “And now here I am, three years later and I think I am ready to do this.”

The Canadian singer reveals it’s been a struggle, but she’s looking forward to getting back to a routine.

“It’s been uphill, just slow, it’s been gnarly, but I have my life back,” she admits. “I can do music, ride my bike and walk again.”

The 33-year-old has been channelling her health challenges into new music, revealing she’s now ready to share it with the world.

“I’ve gone through a lot so to be able to go through my music and write songs I still have that love and passion,” she says.
