Selma Blair is updating fans on how she is dealing with her multiple sclerosis. The American Crime Story star posted a shot of herself snuggled up with a stuffed bear in bed, gazing straight at the camera.

“There is a truth with neurogedenerative brain disease,” she explained in the Instagram post's caption. “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.”

She continued: “People write me asking how I do it. I do my best. But I choke with the pain of what I have lost 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.”

The 46-year-old then explained how she deals with her symptoms.

Blair wrote: “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.”

Blair shared her M.S. diagnosis in December.
