Christina Applegate admits her teenage daughter has lost the mother she once knew to MS

Christina Applegate says her battle with MS has "broken" her daughter Sadie.

The Dead to Me star was diagnosed with multiple sclerosis (MS) - a chronic autoimmune disease that affects the brain and central nervous system - in 2021, and she has detailed how her 14-year-old girl has struggled to see her mom lose control of her movement as she's gotten older.

Speaking to co-host Jamie Lynn Sigler on their podcast MeSsy, she said: "In my situation, Sadie only knew me as healthy, and a runner, and a Pelotoner and a dancer, and she only knew that.

"So then when this came about, 2021, she was like stoic about it.

"And now, I see her look at me when I'm in bed and can't quite move, or I wanna go say goodnight to her in her room, but I can't quite get down the hallway for whatever reason that my legs aren't working that day. Right now I can barely get to bathroom, it's the worst, but that's neither here nor there. It's broken her.

"She didn't know this. It was like losing the mom she had to this f****** thing. And the more she's gotten older now, I think the more it's hurting her."
