The 24-year-old penned a heartbreaking tribute to her dad Treat Williams, one month after the Everwood actor died in a motorcycle accident at age 71.

"I have never experienced this kind of grief before, so it's hard to put my thoughts into words, but I'll try my best for now," Ellie wrote on Instagram July 12. "I have been home with my family in Vermont for a month now, but it feels like just yesterday that I frantically got on a plane home after I got that phone call."

"It feels like he's just away filming," added Ellie, touching on her father's decades-long career. "However, I keep forgetting that he's not coming home this time."

Ellie then gave a nod to the special bond her and the Chesapeake Shores actor had.

"Dad, I love you more than words could ever describe," she wrote. "You have given me the best life imaginable, and I could not have ever dreamed of having a better father. Thank you for loving me completely. I know you will walk with me by my side for eternity."
