Singer Avril Lavigne said she’s seeing progress in her treatment for Lyme disease, which struck her last year while she was on tour. The Canadian singer, known for multiple hits in the early 2000s, said trying to get a diagnosis was the worst time of her life.

Singer Avril Lavigne said she’s seeing progress in her treatment for Lyme disease, which struck her last year while she was on tour. Her treatment regimen has included multiple antibiotics and ample rest. “I'm about halfway through my treatment,” the Canadian singer said in an interview with ABC News’ Jesse Palmer. "I'm doing a lot better. Seeing a lot of progress. ... I'm just really grateful to know that, like, I will make [a] 100 percent recovery."

In 2015, she also went through a divorce from Nickleback singer Chad Kroeger.

Update 2018: Avril does seem to be in good health and high spirits now, so it's likely the Canadian star will take the new album on tour in 2018.

But she hasn’t made any official album date and tour announcements yet...

Lavigne was diagnosed with Lyme disease in 2014 and was bedridden for five months. The "Sk8er Boi" singer says her long awaited new music -- which she's been working on for three years -- will reflect her life-changing journey.

"I'm feeling a lot better," she says about her current health. "It's been a long time. For me to be able to be here and I'm making a record right now. I have my life back which is amazing. It's something I continue to work at every day. And just, like, grateful to be making music. I've written a really powerful record, really emotional album sort of reflecting where I am today. I'm going to release that this year. I'm actually going to be done in two weeks."

"I mean, I write all of my songs and I always have, and these songs are different," she adds. "I'm just sort of writing about what I'm going through now."

In December 2016, Lavigne announced a new album that was originally scheduled to be released in 2017. She also thanked fans for their "patience" while she took time away from the spotlight to prioritize her health.

"I wanted to first thank my fans for your patience and support during my time away throughout my battle with Lyme Disease over the past two years," she posted to Instagram at the time. "It hasn't just been a hard battle but it's also been enlightening and will reflect in my new music, artistry, life, and personally."

Last August, she also gave an update on her new music, explaining that she was taking the time to make sure it's "perfect" for her fans.

"I just want to thank everyone for their patience as I work on putting together this new album," Lavigne Instagrammed. "It's been a long recovery and I want to make sure that this is perfect for you guys!"
