Christina Applegate Says 'Isolating' Is the Way She's Coping With Her MS Diagnosis

Christina Applegate talks about how she's coping with her MS diagnosis in a preview for an upcoming sit-down on 'Good Morning America.' Alongside her 'Messy' podcast co-host, Jamie-Lynn Sigler, the actress tells 'GMA's' Robin Roberts, 'Right now, I'm isolating and that's kinda how I'm dealing with it is by not going anywhere, because I don't want to do it. It's hard.' Christina and Jamie's full interview airs Wednesday on ABC.
