Christina Applegate says MS has left her mostly confined to bedroom, impacting life as a mom

Not only has Christina Applegate's debilitating illness mostly confined her to her bedroom, but it has impacted her ability to parent.

The 54-year-old actress — who is currently promoting the release of her upcoming memoir, "You With the Sad Eyes" — detailed how her multiple sclerosis has affected her ability to parent her 15-year-old daughter, Sadie, whom she shares with husband, Martyn LeNoble. 

"I want to take her [to school and activities]; it’s my favorite thing to do," Applegate told People magazine.
