Sarah Michelle Gellar says she struggled with postpartum depression

May 10 (UPI) -- Sarah Michelle Gellar struggled with postpartum depression following the birth of her first child.

The 40-year-old actress said in an Instagram post Tuesday that she sought help for the condition after delivering daughter Charlotte with husband Freddie Prinze, Jr., in 2012.

"Having kids is wonderful, and life changing, and rarely what you're prepared for. I love my children more than anything in the world. But like a lot of women, I too struggled with postpartum depression after my first baby was born," Gellar wrote.

"I got help, and made it through, and every day since has been the best gift I could ever have asked for. To those of you going through this know that you're not alone and that it really does get better," she added.

Gellar and Prinze, who married in 2002, also share 4-year-old son Rocky. The actress discussed the pressures and challenges of being a working mom in an interview with People in April 2016.

"I feel like home and work balance is an ever evolving process. Most importantly, wherever I am, I know I need to give 100 percent of myself," she said.

"When I am at home, I need to put the phone down and be focused, and when I am at work, that deserves my undivided attention," the star added. "I also need to acknowledge that I am only human, and at times I am spread too thin and need to give myself a moment of down time."

Gellar is known for playing the title character on Buffy the Vampire Slayer, and has since starred on Ringer and The Crazy Ones. She said in a Build interview in April that she doesn't think Buffy would work well as a revival.
