And a year ago, in April, John and I started our family together. We had our daughter, Luna, who is perfect. She is somehow exactly me, exactly John, and exactly herself. I adore her.

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.” During pregnancy, what I thought were casual comments about IVF turned into headlines about me choosing the sex of my daughter. And I can already envision what will be said about me after this admission. But it’s such a major part of my life and so, so many other women’s lives. It would feel wrong to write anything else. So here goes.

I had such a wonderful, energetic pregnancy. Luna sat inside me like a little cross-legged Buddha facing toward my back for nine months. I never saw her face in a sonogram, just her butt or the back of her feet. Every time we kinnnnd of saw a nose, she would quickly dodge, and I was left guessing again. John, my mom, and my sister were all in the delivery room. John was DJ-ing. Luna, fittingly, popped out to the song “Superfly.” The first lyric is “Darkest of night. With the moon shining bright.” I immediately put her on my chest. And she had a face! I was so happy. And exhausted.

After I had Luna, our home was under construction, so we lived in a rental home, then a hotel, and I blamed whatever stress or detachment or sadness I was feeling at that time on the fact that there were so many odd circumstances. I remember thinking: “Maybe I’ll feel better when we have a home.”

I went back to work on Lip Sync Battle in August, when Luna was four months. The show treated me incredibly well—they put a nursery in my dressing room and blew up photos of Luna and John and my family for my wall. When Luna was on set, they lowered the noise levels. They turned down the air so she wouldn’t be cold. Only the most gentle knocking on the door. Pump breaks. I mean, there was no better place to get to go back to work to.

But I was different than before. Getting out of bed to get to set on time was painful. My lower back throbbed; my ­shoulders—even my wrists—hurt. I didn’t have an appetite. I would go two days without a bite of food, and you know how big of a deal food is for me. One thing that really got me was just how short I was with people.

I would be in my dressing room, sitting in a robe, getting hair and makeup done, and a crew member would knock on the door and ask: “Chrissy, do you know the lyrics to this song?” And I would lose it. Or “Chrissy, do you like these cat ears, or these panda hands?” And I’d be like: “Whatever you want. I don’t care.” They would leave. My eyes would well up and I would burst into tears. My makeup artist would pat them dry and give me a few minutes.

I couldn’t figure out why I was so unhappy. I blamed it on being tired and possibly growing out of the role: “Maybe I’m just not a goofy person anymore. Maybe I’m just supposed to be a mom.”
