Kelley Mack Relearning to Walk Before Death Captured in Powerful, Heartbreaking Clip

When someone from The Walking Dead universe leaves us, it always hits a little differently. That show is about surviving impossible odds — about pushing forward when everything around you says stop. In real life, Kelley Mack lived that message until the very end.

The actress, who played Addy in The Walking Dead, passed away on Aug. 2, 2025, at just 33 years old. In the months before her death, she gave the world a deeply personal glimpse into her private battle with cancer. One clip stood out — a raw, emotional video of Kelley Mack relearning how to walk before her death. It was quiet, unpolished, and unforgettable.

There was no filter. No music. Just Kelley, climbing the staircase while gripping the railing for support. Her boyfriend, Logan, followed closely behind her. She, however, clarified that he was NOT helping her up the stairs. He doubled down by pointing out he was just spotting her in case she fell.

She was moving slowly, every step clearly difficult, but she was doing it anyway. She even captioned the post with a joke: “Life has had its ups and downs lately am I right lol.” That sentence alone told you everything — her pain, her perseverance, and her refusal to lose her sense of humor.

Her humor also made an appearance at the end of the video when she joked about having twigs for legs despite constantly hitting the gym just because she “spent a month in bed.”

As Kelley had revealed via her Instagram previously, she had been diagnosed with diffuse midline glioma, a rare and aggressive brain and spinal tumor that quickly took her mobility. After a spinal biopsy, she lost function in her right leg and most of her left. That clip of her walking again showed just how much she was willing to fight to keep moving, even when everything hurt.

Kelley didn’t frame her updates as inspirational. She didn’t ask for sympathy. Her Instagram became a personal record of what it looks like to live inside of something hard. She posted photos from treatment. Updates from physical therapy. Moments of work and rest and trying, trying, trying. The walking video wasn’t the only proof of her strength — but it might’ve been the one that broke the internet’s heart.

That’s what made Kelley’s posts so powerful. She didn’t turn her diagnosis into content. She didn’t wrap it in inspiration. She let it be messy. Sometimes she looked exhausted. Sometimes she laughed through it. Furthermore, her fans loved the way she frequently used humor to cope with her ongoing health struggles.

Maybe you didn’t know Kelley until now. But if you’ve seen the video, you know enough. You know she showed up. That she tried. That she made it count, even when it hurt. Both her fans and her loved ones were there beside her, cheering her on until the end.
