The post included photos of Sadie growing up, family gatherings, sweet selfies and even a shot of the teen dancing with Patridge at her 2016 wedding to Corey Bohan.
One particularly heartbreaking video showed the reality TV personality, Sadie and Sadie’s mom, Casey Loza, smiling and laughing for the camera.
Neither Patridge nor her sister — who also appeared on “The Hills” and “The Hills: New Beginnings” — revealed the cause of Sadie’s death, but Loza told her own Instagram followers that her daughter’s “story will save countless lives.”
She agreed with Patridge that making the announcement was unbearably painful, explaining, “Writing this was the hardest thing I ever have had to do.”
“Sadie liked to remind me that the first law of thermodynamics aka (Law of Conservation of Energy) works in all spheres of life….. ‘Energy cannot be created or destroyed, it can only be changed from one form to another,’” the grieving mother penned. “Transformation is a better word than death.”
Loza concluded her post, “Rest In Peace you brilliant starseed. You’re with your creator. We will miss you dearly. I love you.”
