Christina Applegate had heartbreaking admission after filming hit Netflix show with MS diagnosis

Christina Applegate had a heartbreaking admission after filming one hit Netflix show with her MS diagnosis.

The 52-year-old actor was diagnosed with multiple sclerosis in the summer of 2021 while working the third and final season of the comedy-drama.

She has since opened up about her health issues in order to help shine a light on MS by revealing that her symptoms dated back years before she actually knew what she was dealing with.

Recalling the time she was diagnosed, Applegate told the LA Times that she was a 'wreck' every single day, adding: "Most of that wreck would take place in my trailer by myself."

She continued: "But there were times I’d break down on set and be like, 'I can’t, we have to take a break, I need a half hour', and everyone was so loving that it was okay."

The season in question, which began filming in May that year was then forced to put a hold on production until August and the production, only wrapped early the following year.

If you hadn't already guessed it, the TV series in question was none other than Dead to Me which landed on Netflix in November 2022.

It was difficult for Applegate to watch the final season as she revealed: "I don't like seeing myself struggling.

"Also, I gained 40 pounds because of inactivity and medications, and I didn't look like myself, and I didn't feel like myself."

Applegate went on: "At some point, I was able to distance myself from my own ego and realise what a beautiful piece of television it was.

"All the scenes I wasn't in were so much fun to see and experience for the very first time."

Applegate previously recalled being able to 'brush off' the symptoms in January 2021, but just before she started shooting the third season of Dead To Me, she felt as though she had been 'hit by a truck and didn’t know what was going on'.

Speaking to Variety, Applegate continued: "It was very scary for me, because this body that I had known was no longer mine.

"We had to kind of work around that until, finally, I had answers.

"I found that I had MS while we were shooting on a Monday. I went home, and the doctor said, 'I need to do this meeting with you'.

"I could feel that this Zoom was not going to be good news. It sucked, I’m not going to lie."
