“13 Reasons Why” star Kate Walsh recently revealed that she was diagnosed with brain tumor two years ago.

In an interview with Cosmopolitan, Walsh said that one of the symptoms she experienced in 2015 was extreme exhaustion. But she initially thought it was normal because she was working 80 hours per week and was also working out a lot.

A few days passed and things did not get better for the “Grey’s Anatomy” star that she decided to change her workout routine. “I figured, okay. I’ll change up my working routine, I’ll go back to mellow stuff like hiking,” she said. But during her Pilates session, her instructor noticed that the right side of her body was dipping.

“Then when I was driving, I started swerving into the right lane. The exhaustion got to the point where I could drink five cups of coffee and still not feel awake or clear. And then around April, I started having more cognitive difficulties. It felt like aphasia, but it wasn’t just not being able to find words; I would lose my train of thought, I wasn’t able to finish sentences, and that was when I got really alarmed. I thought maybe it was menopausal symptoms, because there are a lot of the same markers, but I really pushed to see a neurologist, I just had an instinct,” she said.

Walsh visited his doctor and was told that she had a meningioma the size of a lemon and had to undergo surgery. Following the procedure, Walsh learned that her brain tumor was benign.

Meanwhile, Walsh has also partnered with Cigna as part of their TV doctors campaign to encourage more people to get their annual checkups and advocate their own health. Part of the campaign is Walsh’s former TV husband, Patrick Dempsey and “How I Met Your Mother” alum Neil Patrick Harris.

Following her surgery, she also took nine months off from work, but returned to star in “13 Reasons Why” and “Felt.” Despite her busy schedule, the actress makes it a point to sleep for seven to eight hours every night as part of her recovery.
