Avril Lavigne is a fighter.

The singer has been open about her battle with Lyme disease, and recently took to Instagram to share an update with fans about her ongoing journey to recovery.

"On my way to good health #TakingCareOfMyself #FuckLymeDisease," Lavigne wrote with a photo that showed 13 vials of her blood (eek!).

Lavigne also shared another snapshot of herself waiting to get checked up by the doctor, with the caption, "This journey continues ..... Just reach up, don't give up until you've touch the sky ..... We were all meant to fly .... #DrOfficePhotoShoot @Hurley @amusesociety."

Despite having to undergo such an unfortunate event, the blue-eyed beauty seemed to be in good spirits, flashing a smile for the camera while strutting her usual, casual gear and a pair of flip-flops that spelled out "Love."
