It's been four months since Selma Blair revealed on Instagram that she'd been diagnosed with multiple sclerosis (MS), a serious and chronic neurological disease. (Apparently, she took a 23andMe test that hinted at a diagnosis years ago.)

"I have #multiplesclerosis," she wrote in the post. "I am in an exacerbation. I am disabled. I fall sometimes. I drop things. My memory is foggy. And my left side is asking for directions from a broken GPS. But we are doing it."

Last night, the actress made her first red carpet appearance at the Vanity Fair Oscars After Party since sharing her diagnosis and she was nothing short of a vision. Wearing a gorgeous Ralph Lauren gown, Blair teared up as she stepped in front of the cameras, using a cane for assistance. "It took a lot to come here," she said on the red carpet as people cheered her on.

She then took to Instagram today to share her gratitude towards her former publicist, turned manager and best friend Tory Nankin who helped her as she stepped onto the red carpet more nervous than ever. "It was a streak of light to say I am here," she wrote. "I am still in an exacerbation so there was some nervousness. I don't do anything the way I was once able. I will though. I can regain much. Mommas gotta work. And I will be able to do so much more on my own, But this man. Until that comes, this man and a host of others light the way and hold the moon. [He] was a hero wanting me to shine brightly in a time that can be so challenging. He knew I wanted to be able to stand proudly as the woman I have become and hope to be. To be a part of something so special when my body won't move clearly yet."

She added how the experience as a whole was something she'll cherish forever. "I felt the love from the photographers who have watched me goof around on red carpets since I was in my twenties," she wrote. "I felt the warmth of the bulbs. The strength of my gown. His attentive touch. And still I hoped my brain could send signals for the remainder of my time there. And I sobbed. And I appreciated every single second. Every surprising tear, he was there. As he has always been. And that is the reason I could. Thank you Troy. We got me just where I wanted to be. For a night. So much to post but not before this one. True love. Right here. Forever."​

MS is a progressive neurological disease that occurs when there's a breakdown in communication between the brain and other parts of the body, according to the National Institutes of Health (NIH). The exact cause is unknown and the disease presents itself differently for everyone. However, since it's two to three times more common in women, hormones may play a role, according to the National Multiple Sclerosis Society. Common symptoms include blurred vision and difficulty with coordination and balance. (Read more about one woman's experience with MS in Fitness Saved My Life: From MS Patient to Elite Triathlete)

Blair is one of the 400,000 people living with MS in the United States, according to NIH. By being candid about her journey, she's hoping to provide other sufferers with support.

"I am in the thick of it but I hope to give some hope to others," she previously shared on Instagram. "You can't get help unless you ask. It can be overwhelming in the beginning. You want to sleep. You always want to sleep. So I don't have answers. You see, I want to sleep. But I am a forthcoming person and I want my life to be full somehow. I want to play with my son again. I want to walk down the street and ride my horse. I have MS and I am ok. But if you see me, dropping crap all over the street, feel free to help me pick it up. It takes a whole day for me alone. Thank you and may we all know good days amongst the challenges."
