Jack Schlossberg Still Can’t ‘Process’ Sister Tatiana’s Death: ‘World Will Never Be the Same’

In a New Yorker essay published in November 2025, Tatiana wrote that she had been given a year to live after receiving her devastating diagnosis.

Tatiana shared that she learned she had “a rare mutation called Inversion 3” after her doctor noticed an imbalance in her white blood cell count following the birth of her second child. Initially, Tatiana was told she would need to undergo months of chemotherapy and receive a bone marrow transplant.

“I did not — could not — believe that they were talking about me. I had swum a mile in the pool the day before, nine months pregnant. I wasn’t sick. I didn’t feel sick. I was actually one of the healthiest people I knew,” she wrote. “I had a son whom I loved more than anything and a newborn I needed to take care of.”

Tatiana added in the essay that her mind immediately went to her young children and she shared her fears that they would grow up with limited memories of their mother.

“My first thought was that my kids, whose faces live permanently on the inside of my eyelids, wouldn’t remember me,” she recalled. “My son might have a few memories, but he’ll probably start confusing them with pictures he sees or stories he hears. I didn’t ever really get to take care of my daughter — I couldn’t change her diaper or give her a bath or feed her, all because of the risk of infection after my transplants. I was gone for almost half of her first year of life. I don’t know who, really, she thinks I am, and whether she will feel or remember, when I am gone, that I am her mother.”
