\"I kinda got to a critical point and my nervous system and more symptoms and I couldn't stay awake,\" Blair said. \"I was mortally afraid of chemo my whole life. I'm someone that's always gone holistic when I can.\"

But Blair said that after one dose of chemo, she was talking clearly and the inflammation started to go down. Now, she revealed her brain is free from forming new lesions, but she does have volume loss in some speech and movement areas and prefrontal damage -- things she takes medicine for throughout the day.

\"I chose this as a marker in my life to want to live, to want to be a person that can show other people with chronic illness, disabilities, an injury they couldn't get over, a hit,\" she said. \"I just took a hit. And we take hits. ... And that resilience is possible.\"

As for acting, she hopes it's something she can return to someday.

\"If the right thing -- I'm not looking, but God knows I would never say I wouldn't dream of being a part of an amazing set one day.\"

For now, she's taking things one step at a time and finding joy.

\"We have to take care of ourselves and be patient,\" Blair said. \"And better times come. Maybe not for good. Maybe it's not a cure. But more than not, better times will come. We're meant to have joy on this earth. I never felt that before.\"

\"Introducing, Selma Blair\" will hit theaters Oct. 15 and streams on Discovery+ starting on October 21.
