Dia Dipasupil/Getty Images(NEW YORK) —  Actress Selma Blair is once again shining a light on the struggles of her multiple sclerosis (MS) journey. But she’s also inspiring others in the process.

Since being diagnosed last summer, Blair has been a trailblazer in raising awareness about the diseases, never holding back about what she’s been going through over the past year.

On Friday, she posted a photo to Instagram, in bed, looking sullen and worn down after having gone through medical treatments.

Here’s a truth. 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. And to moms and dads who watch their kids sick on things we take to get better… I hold you. So glad this is me and not my child. I cannot imagine ever feeling ok again. #roughday. We get through. #realitycheck

“Here’s a truth. I feel sick as all hell,” she wrote. “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.”

She went on, “I am going to get through this. We do. This will pass. And to moms and dads who watch their kids sick on things we take to get better… I hold you. So glad this is me and not my child. I cannot imagine ever feeling ok again. #roughday. We get through. #realitycheck.”

As can be expected, hundreds of her fans are sending “healing vibes” her way in the comments section, among other supportive messages.

The honesty and grace at which she battles her multiple sclerosis is nothing new.

In February, Blair spoke to “GMA,” opening up about the mental and physical challenges of the disease, especially after going almost seven years without a diagnosis.

When she finally was able to get a definitive answer last August, “I had tears,” she said. “They weren’t tears of panic. They were tears of knowing I now had to give in to a body that had loss of control, and there was some relief in that.”

There is a truth with neurogedenerative brain disease. It is uncomfortable. It is a stadium of uncontrollable anxiety at times. Going out, being sociable holds a heavy price. My brain is on fire. I am freezing. We feel alone with it even though the loving support has been a god send and appreciated. People write me asking how I do it. I do my best. But I choke with the pain of what I have lost (riding) and what I dare hope for. and how challenging it is to walk around . But my smiles are genuine. This is ok. Life is an adventure with many shards of awakening. I can’t sleep at night but daytime I have trouble staying awake . I am a grown woman holding onto a bear that belonged to a sister type of mine. ( thank you @k.d.w.r ) we do what we can. I have a full week ahead with mothering and appointments and things to look forward to. But like many of us, I am praying. Soaking in love where I can. It’s not easy. That’s ok. I send love to you. And by the way, this #eileenfisher sweater is my go to cozy tonight in this hotel room. Thank you. And @lorrigoddard_ I can’t thank you enough for the morale boost of blonde. And to my love @mrchrismcmillan #humancondition #strengthinvulnerablity #MS #stillanactress #always #willmakeitwork #heartwideopen ❤️ #thisisforallofus. #littlethings PS. Some outlets use quotes as clickbait of suffering. My life is not about suffering. These are moments of sharing in a way that some may find too much, but there is positivity in these posts. A face to a disease I could not get information about from people I saw succeeding. I am succeeding and love my life. It is doable to have some rough moments and express it. No?

“Ever since my son was born, I was in an MS flare-up and didn’t know, and I was giving it everything to seem normal,” Blair told Robin Roberts in the interview. “And I was self-medicating when he wasn’t with me. I was drinking. I was in pain. I wasn’t always drinking, but there were times when I couldn’t take it.”

In addition to her candid interviews, Blair has been vocal on Instagram, trying to help anyone out there who may be living with MS or any other illness. Fellow MS sufferers have thanked the actress for shedding light about the struggles with the disease.

“There is a truth with neurodegenerative brain disease. It is uncomfortable. It is a stadium of uncontrollable anxiety at times,” Blair wrote on Instagram in January. “Going out, being sociable holds a heavy price. My brain is on fire. I am freezing. We feel alone with it even though the loving support has been a god send and appreciated. People write me asking how I do it. I do my best.”
