Serena Williams opened up about what led her to pull out of the Rogers Cup.

On Saturday, August 4, the tournament announced Williams would not compete, citing “personal reasons,” according to The Associated Press.

Williams revealed those reasons in a candid Instagram post where she detailed her struggle with postpartum emotions:

Last week was not easy for me. Not only was I accepting some tough personal stuff, but I just was in a funk. Mostly, I felt like I was not a good mom. I read several articles that said postpartum emotions can last up to 3 years if not dealt with. I like communication best. Talking things through with my mom, my sisters, my friends let me know that my feelings are totally normal. It’s totally normal to feel like I’m not doing enough for my baby. We have all been there. I work a lot, I train, and I’m trying to be the best athlete I can be. However, that means although I have been with her every day of her life, I’m not around as much as I would like to be. Most of you moms deal with the same thing. Whether stay-at-home or working, finding that balance with kids is a true art. You are the true heroes. I’m here to say: if you are having a rough day or week–it’s ok–I am, too!!! There’s always tomm!

At the end of the post, she expressed solidarity with other mothers who face similar insecurities.

“Whether stay-at-home or working, finding that balance with kids is a true art. You are the true heroes,” she said.

This the second time Williams spoke about motherhood this week. In an interview with Essence, she gushed about baby Olympia’s excitement to see her mommy.

“Well, every moment…every morning when she first sees me, she squeals,” Williams said. “Every day, I’d come home from one of my matches and Wimbledon, and she’d just squeal each time she’d see me. I’d try my best to rush home, and I’d miss her still. It’s like nothing I’ve ever heard before—the best thing I’ve ever heard.”
