Marnie Schulenburg has died after a two-year battle with stage four metastatic breast cancer.

The soap opera actress—known for her roles as Jo Sullivan in the One Life to Live reboot and Alison Stewart in As the World Turns—passed away on May 17 at age 37, her rep Kyle Luker confirmed to The Hollywood Reporter.

She's survived by her husband Zack Robidas—who acts in Succession and Sorry for Your Loss—and their 2-year-old daughter Coda. Marnie was diagnosed with cancer five months after giving birth to Coda in December 2019, according to THR.

The late actress last posted to Instagram on Mother's Day, sharing that she was able to celebrate the holiday at home after being released from the hospital on May 6. 

The post showed Marnie playing in the park with her daughter and mother by her side, as well as a photo of herself reading to Coda in bed.

"It's not my ideal to be a 38 year old Mom who needs an oxygen tank to survive right now," wrote Marnie, who would have turned 38 on May 21. "I want to be strong and beautiful for her.

I want to show her how to move throughout this world with compassion, strength, vivacity, humor and joy like my Mother showed me."

She explained that while she was in the middle of a two-year battle with cancer, she realized the "best thing you can do for your child is make them feel loved, safe and supported like my mother did for me."

Before her tragic death, the former gymnast also held roles on Elementary, Tainted Dreams, City on a Hill, Royal Pains and Blue Bloods.

 In addition to being an actor and mother, she described herself as the "partner to the best man ever" and the "owner of an evil cat."
