Michelle Trachtenberg “knew that death was a high possibility,” her friend Amanda de Cadenet said.

The photographer recalled speaking to Trachtenberg in the months before the “Gossip Girl” alum’s death Wednesday.

“Sweetheart Michelle.

What sad news this morning to wake up to. It feels weird and awful to be posting this, but I want to acknowledge your death because I cared about you,” de Cadenet wrote via Instagram.

“I will always remember you as the young vivacious woman I met when I took this photo of you … and seeing your face from the hospital bed when we FaceTimed recently, even though you did not look like you, your sweetness and humor were still alive.”

De Cadenet, 52, went on to share insight into her private discussions with the “Buffy the Vampire Slayer” actress.

“I will not share the details of our conversations over the last 6 months, but you knew that death was a high possibility and I am only sorry that the outcome was not a better one,” de Cadenet continued.

“Wishing you a peaceful transition sweet friend and may your spirit finally rest.

Along with her tribute, De Cadenet shared a photo she took of Trachtenberg posing in a strapless pink dress with a dark smokey eye.

The late actress was found dead Wednesday morning at her New York City apartment after going into cardiac arrest, sources told The Post.

Trachtenberg underwent a liver transplant within the past year, according to sources, who said she died of natural causes. An official cause of death has yet to be released.

An insider also told People Wednesday that Trachtenberg was “struggling” both mentally and physically before her death.

“She told friends she was struggling,” a source said. “She was really, really sick and open with those in her circle about how much she was struggling.”

According to the outlet, friends also noticed the “Ice Princess” star looking “pale, gaunt” and “very thin.”

One year before her death, Trachtenberg clapped back at fans who questioned her physical appearance on social media and said she appeared “sick.”

“Explain to me how I look sick,” she replied. “Did you lose a calendar and not realize I’m not 14. I’m 38. How sad for you to leave such a comment.”

A few weeks later, the “Harriet the Spy” actress shared another selfie to fire back at the “haters.”

“I’ve received several comments recently about my appearance. I have never had plastic surgery I am happy and healthy. Check yourself haters,” Trachtenberg wrote in January 2024.

Many of Trachtenberg’s former co-stars and friends have taken to social media to publicly mourn her death, including fellow “Gossip Girl” alums Blake Lively, Chace Crawford and Ed Westwick.
