Chrissy Teigen is a self-admitted “Over-sharer.” But sometimes over sharing can lead to some pretty remarkable breakthroughs!

In the upcoming issue of Glamour Magazine the 31-year-old model and author wrote an emotional letter where she disclosed her recent struggles with postpartum depression after giving birth to daughter Luna last April.

She wrote, “For much of the last year, I felt unhappy. What basically everyone around me ¬– but me – knew up until December was this: I have postpartum depression”

She goes on to admit that even though she’s always smiling, it doesn’t mean she’s happy.

“Postpartum does not discriminate. I couldn’t control it,” she added. “And that’s part of the reason it took me so long to speak up: I felt selfish, icky, and weird saying aloud that I’m struggling.”

For Chrissy, speaking her mind has become somewhat second nature but she struggled to announce this difficult news. And now she has some parting advice for her fans.

“I’m speaking up now because I want people to know it can happen to anybody and I don’t want people who have it to feel embarrassed or to feel alone. Just merely being opening about it helps. This has become my open letter.”
