I was in this wardrobe fitting two days ago. And I am in the deepest gratitude. So profound, it is, I have decided to share. The brilliant costumer #Allisaswanson not only designs the pieces #harperglass will wear on this new #Netflix show , but she carefully gets my legs in my pants, pulls my tops over my head, buttons my coats and offers her shoulder to steady myself. I have #multiplesclerosis . I am in an exacerbation. By the grace of the lord, and will power and the understanding producers at Netflix , I have a job. A wonderful job. 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 . And I laugh and I don’t know exactly what I will do precisely but I will do my best. Since my diagnosis at ten thirty pm on The night of August 16, I have had love and support from my friends , especially @jaime_king @sarahmgellar @realfreddieprinze @tarasubkoff @noah.d.newman . My producers #noreenhalpern who assured me that everyone has something. #chrisregina #aaronmartin and every crew member... thank you. I am in the thick of it but I hope to give some hope to others. And even to myself. 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. And the biggest thanks to @elizberkley who forced me to see her brother #drjasonberkley who gave me this diagnosis after finding lesions on that mri. I have had symptoms for years but was never taken seriously until I fell down in front of him trying to sort out what I thought was a pinched nerve. I have probably had this incurable disease for 15 years at least. And I am relieved to at least know. And share. ?? my instagram family... you know who you are.

MS is a disease of the brain and spinal cord (or central nervous system), according to The Mayo Clinic. Currently, there is no cure for the disease, but there are treatment options that can help modify the course of the disease and manage symptoms, according to the clinic's website.

The neurodegenerative disorder can cause problems with speech, motor functions and also vision, according to ABC News' chief medical correspondent Dr. Jennifer Ashton.

The cause of the disease is unknown, but many people with MS experience a waxing and waning course of ups and downs and highs and lows that can vary vastly between different people, Ashton added. The key is managing MS, as is it is a chronic condition.

One of the biggest difficulties people dealing with MS may face is that we often have a problem dealing with things we can't see, and as MS is a brain condition, you often cannot outwardly tell if someone is suffering from it, according to Ashton.

Support groups and awareness can really help with this, she added, as well as seeking out mental health treatment with counselors or therapists, as MS can often carry with it an emotional toll.
