A year after announcing her pregnancy loss, Chrissy Teigen is finally opening up about how she still struggles to process the memory of her unborn son.

On Sunday, the 35-year-old reflected on the past year, which she described as a "rollercoaster," as she shared a photo of her and husband John Legend enjoying a cozy dinner at one of their favorite spot in New York City.

In a lengthy caption, she talked about the restaurant.

"We've been going to @frankrestaurant for…man, maybe 13, 14 years now?? we used to live just a couple blocks away, right across from the hell's angels in the east village. John had a basement apartment with a roommate and I used to sneak cigarettes (ew) through the little half window that lined up with the sidewalk. basically a window where you could only see people’s shoes. anyhow I'd either drag puddy's big ass to sit outside at frank, or sometimes sit at the kitchen bar alone, reading Glamour and trying everything on the menu. And I would never ever miss a Thursday," she said.

Reminiscing about days when things were much simpler, she wrote, "Just reminiscing about New York a lot lately, when things were simple, thinking about all the stuff I've done and been through not just this year but in my life."

The cookbook author shared that she felt a bit down when she tried to think of a suitable caption for her book, which unfortunately reminded her of her third child.

"I'm slightly down lately. It kind of started when I was thinking of my book caption and typed out 'my third baby is here!!,' as in cookbook, then realized my third baby will never be here. then I realized I threw myself into the book to not think of the real, actual third baby. I don't really feel like I fully processed jack and now that I don't have the alcohol to numb it away, things are just…there, waiting to be acknowledged. I guess what I'm saying here is life is so f---ing complicated. and get the lasagna??? wow this was a rollercoaster !!!!!" the television personality wrote.

Last weekend, Teigen released her third cookbook, titled "Cravings: All Together: Recipes To Love Friday," which she dedicated to her late child Jack.

Teigen lost her son at 20 weeks in late September 2020. The couple shared the devastating news on Instagram in October.

Teigen and Legend have a 5-year-old daughter, Luna Simone, and a 3-year-old son, Miles Theodore.
