• Jamie-Lynn Sigler opens up about her struggles with MS in an episode of Shondaland's podcast Katie's Crib hosted by Katie Lowes, which will air next week.
  • The 37-year-old actress was diagnosed when she was 20, but didn't reveal it publicly until January 2016.
  • Sigler shares the challenges, both mentally and physically, of having the unpredictable disease.

It's been 17 years since she was diagnosed with Multiple Sclerosis, but actress Jamie-Lynn Sigler is now opening up about how she still struggles to cope with the disease.

In a new episode of Shondaland's podcast hosted by Scandal alum Katie Lowes airing next week, the 37-year-old actress gets candid about how she still struggles with being okay with her body, People reports . Even now when I work, which is very rare, I still deal with this - wanting to look normal, wanting to cover [my MS] up, because thats what I did for so many years, she tells Lowes.

I think Im still coming to terms with owning it, and being okay with knowing this is just my body and how I move, she added.

Multiple sclerosis (or MS as it's more commonly referred to) is an "unpredictable, often disabling disease of the central nervous system that disrupts the flow of information within the brain, and between the brain and body," according to the National Multiple Sclerosis Society .

Last month, Jamie-Lynn shared a touching tribute on Instagram to her "new friend" Selma Blair, who was diagnosed with MS in August 2018.

View this post on Instagram Selma, you are a new friend, but your heart, bravery and courage makes us ALL feel so close to you. This woman brings everyone another step further in feeling represented, understood and unafraid. Pls watch her incredible interview on GMA this morning if you havent. She said things better than many of us ever could. #warrior @selmablair A post shared by Jamie Lynn Sigler (@jamielynnsigler) on Feb 26, 2019 at 4:04pm PST

"Selma, you are a new friend, but your heart, bravery and courage makes us ALL feel so close to you," Sigler writes in the post. "This woman brings everyone another step further in feeling represented, understood and unafraid. Pls watch her incredible interview on GMA this morning if you havent. She said things better than many of us ever could."

While Sigler still battles with how her disease will impact the lives of her two young children and her family, she opened up last year about how she is learning to cope.

With my MS, the one thing that its given me, which Im trying to focus more on what its given me as opposed to what its taken away, is its led me on this spiritual path that I really dont think I would have gone down, she said on the DENtalks Podcast . It was really just an opportunity for me to look within. Because when you feel like your bodys kind of betraying you and youre losing control despite your best efforts, like the only way to find any sort of strength is just like within and I still work on it.
