Story highlights Rare form of cancer claimed 4-year-old Nolan's life after a year of treatment

Mom says her son would have liked his friends to know what happened

(CNN) It's been two months since Ruth Scully lived every parent's nightmare. Now, she is sharing her story on Facebook in hopes that it can bring change.

On February 4, 2017, Scully's son Nolan lost his battle with Rhabdomyosarcoma, a rare form of cancer that affects soft tissue. In an ode to her son, Scully shared a photo collage on Facebook showing the harsh realities of childhood cancer.

She explains that during his struggle 4-year-old Nolan refused to leave her side, even lying on the bathroom floor when she showered.

The first picture shows Nolan on a bathmat. It was taken before he left for the hospital to start an aggressive chemotherapy regimen. The second picture, taken on the two-month anniversary of his death, shows the same bathmat, this time without Nolan.

"Now I'm the one terrified to shower," Scully wrote in her post. "With nothing but an empty shower rug now where once a beautiful perfect little boy laid waiting for his Mommy."
