Actress and voiceover artist Kelley Mack, best known for her role as Addy on The Walking Dead, has died at age 33. The family of the actress shared the news on Mack’s official Instagram page on August 5.

“It is with indelible sadness that we are announcing the passing of our dear Kelley. Such a bright, fervent light has transitioned to the beyond, where we all eventually must go,” the post read.

Last winter, Kelley revealed that she was undergoing treatment after being diagnosed with a rare form of cancer. In January, she wrote in a post: “In September, I moved into a new apartment with my boyfriend, Logan. For a month after that, I had persistent lower back pain and thought I slipped a disc. A few weeks later, I had neuropathic itching in my right quad. And then, the shooting pains in my legs and back began, which resulted in me having to sleep in a recliner for a month because laying down was too painful. On Thanksgiving Eve, I had emergency MRIs done at the hospital, which revealed an abnormal mass in my spinal cord.”

“Fast forward to now – I have been diagnosed with #diffusemidlineglioma, an extremely rare type of #astrocytoma #cancer. Due to the biopsy surgery on my spinal cord, I have lost the use of my right leg and most of my left leg, so I now get around with a walker and a wheelchair.”
