John Legend's wife speaks out about her postpartum depression.

International pop star John Legends wife, Chrissy Teigen has confessed for the first time about her post natal depression following the birth of her daughter, Luna, last year in April.

In an essay for US Glamour, she explained that she discovered she was having postpartum depression in December last year after months of struggling with severe back and wrist pains, eating disorder and work commitment.

It was her return to her TV show Lip Sync Battle four months after having Luna that made her realize that she wasn’t the same person.

“I had everything I needed to be happy. And yet, 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. “How can I feel this way when everything is so great? I’ve had a hard time coming to terms with that, and I hesitated to even talk about this, as everything becomes such a ‘thing’.”

Chrissy said that for long periods of time she found it very difficult to leave the house, shutting herself away in the dark and barely moving from the same spot all day.

"I was so tired of being in pain. Of taking things out on people. Of not enjoying life."

Her husband has on a number of occasions called her a smart mouth. She’s warmed her way to the hearts of many with her bubbly and very open personality. Chrissy who we can comfortably name an over achiever has always looked like she can conquer the world but she says that she found it difficult to open up about her situation because she felt ‘selfish, icky and weird.’

She wrote, “I have all the help I could need: John, my mother (who lives with us), a nanny. “But postpartum does not discriminate. I couldn’t control it. 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. Sometimes I still do.”

“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. I also don’t want to pretend like I know everything about postpartum depression, because it can be different for everybody. But one thing I do know is that for me just merely being open about it helps.”

Chrissy also admitted to still be on medication. She said that said is now taking an antidepressant and is also in therapy signing off on Twitter with this, “Important note: please don't feel like you have to tiptoe around me! It is the most uncomfortable feeling ahhhh only downside to sharing PPD.”
