Back in 2018 actress Selma Blair revealed that she had been diagnosed with Multiple Sclerosis, a disease of the central nervous system that can cause a variety of symptoms including vision loss, pain, fatigue, and impaired coordination. MS affects people differently, with some never experiencing these symptoms and others experience them chronically. Unfortunately for Blair, she seems to be to dealing with the very worst of these symptoms, but she's sharing her experience with fans and followers to educate them more on this disease.

Recently the mother of one took to social media to share a rough day and just how daunting the treatments she's been undergoing for her MS have been on her health, and how they are affecting her personal and professional life.

"Here’s a truth," she began her post on Instagram accompanied by a photo of herself in bed, clearly not feeling great. "I feel sick as all hell. I am vomiting and all the things which are not polite to speak of. My son ran away. From me. I have to get him to school. The medical treatments take their toll. I am going to get through this. We do. This will pass."

Even though the actress is sick she shared that she was more than happy that it was she who was dealing with the pain and not her own son. She sent a message to other parents who have to deal with children who have their own health struggles. "And to moms and dads who watch their kids sick on things we want them to take to get better... I hold you. So glad this is me and not my child. I cannot imagine ever feeling ok again. #roughday. But it’s still morning. We get through. #realitycheck"

Blair is doing what she can to look at her diagnosis with positivity while sharing her very real experiences on social media. She posted a picture the following day where she writes that she got cleaned up and went out, only to get sick. She adds that she ran into fellow actress Sharon Stone who made her feel "comforted."

Blair told NBC news that doctors initially diagnosed her symptoms as exhaustion, missing the MS diagnosis that she would eventually receive. She said she resorted to self-medicating to handle her increasing symptoms. “My physical pain was so extreme that I would drink by myself. That was also a warning to me,” she admitted, “I’ve never been one who handled alcohol like a lady. I was self-medicating.”

It wasn't until almost three years after she noticed her symptoms that she began to get the answers she needed. “There was some relief in that, because ever since my son was born, I was in an MS flare-up and didn’t know. I was giving it everything to seem normal.”

Blair shared a new picture just a few days ago where she writes that she is feeling better and is grateful for all the kind words and thoughts people send her. "Thank you. For caring. And I send all love. See? Things pass. Or you get sick in prettier clothes. Win win. I have the dearest team here. Thank you. Feeling much more life like today. Loving every second."

Blair is helping to not only make herself better by receiving support from friends and fans by sharing her experiences, but she's also providing an opportunity for the public to learn more about MS and how it can affect individuals.
