“Essentially, what I’m describing is hard work with possibly limited success for the rest of your life. But we have to do it, and at least we will have the satisfaction of knowing we made things better…Come on, it will be fun (?),” Schlossberg concluded, in an excerpt from her 2019 book, “Inconspicuous Consumption.”
Jack simply captioned the post with a pink flower.

“I did not — could not — believe that they were talking about me,” she wrote of receiving her diagnosis, in an essay published in The New Yorker. “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.”
Doctors reportedly discovered her disease after she gave birth to her second child in May 2024.
Tatiana Schlossberg was 35 years old.
