The actress, 44, took to Instagram Wednesday to thank her fans and colleagues for their "support" and "encouragement" amid her ovarian cancer battle.

"I can’t do this without so many people getting involved to support me," she wrote, along with a selfie that shows her bald head.

"It’s actually physically impossible! To those who facilitate day in and day out, in order for me to come to work to do what I do, thank you!"

The actress also thanked her colleagues at Wolf Entertainment, the production company behind the "Chicago" shows. 

Barrett has starred on "Chicago Med" since 2015 and appeared on "Chicago Fire" from 2016 to 2019.

"To this extended family around the world, I pray we as people remember how BIG life is and how much LOVE can do in a persons life," she wrote.

 "With that being said.. Tonight’s episode of #chicagomed is special, because it was hard to shoot the first two episodes for me.

I think you will enjoy what we managed to bring together. This encouragement has blown my mind!"

Barrett told People that doctors diagnosed her with cancer in July after finding a football-sized tumor on her uterus and left ovary.

"The best way I could experience was to meet it," she said. "There's no running from it because it's my life.
