That’s what happened to Lavigne, who thought she just had the flu when she started having symptoms in 2014. It took several months for her to get a correct diagnosis.

“I was seeing every specialist, literally the top doctors, and they would pull up their computer and (say) ‘Chronic fatigue syndrome’ or “Why don’t you try to get out of bed Avril and just go play the piano? Are you depressed?’” Lavigne said in an emotional interview on Good Morning America.

“This is what they do to a lot of people that have Lyme disease. They don’t have an answer for them, so they tell them they’re crazy.”

The 33-year old singer eventually found a Lyme specialist who diagnosed her correctly. By then she was bedridden.

“One night, I thought I was dying, and I had accepted that I was going to die. My mom laid with me in bed and held me. I felt like I was drowning,” Lavigne wrote on her website.
