"As long as we have our health, that's all that matters," Giudice tells PEOPLE Now

Though Teresa Giudice and Melissa Gorga‘s family is going through one of the most trying times ever, they are standing strong.

The sisters-in-law sat down with PEOPLE Now to discuss the roller coaster of drama they’ve endured in the last 18 months, much of which will be shown on The Real Housewives of New Jersey this season.

But even amid that drama, Giudice’s primary concern has been maintaining stability for her four daughters – Gia, 15, Gabriella, 11, Milania, 10, and Audriana, 6 – since husband Joe left to serve a 41-month prison sentence for fraud.

While she regrets that Joe, 44, will miss Gia’s Sweet 16 and Milania’s fifth grade graduation, she’s trying to keep this temporary disruption in perspective.

“I think about it like there’s people in the military that are not there for everything,” says Teresa, “Of course he would be there if he could … as long as we have our health, that’s all that matters. When you have your health, you have everything.”

Confirming the change in her sister-in-law’s outlook, Gorga says, “I think she’s different, she has a different outlook on life – she’s calmer.”

And Giudice credits some of that calmness to her new-found love of yoga, which she developed in prison: “[In prison] I did it every day, like twice a day. Now it’s a Monday through Friday thing,” she says, adding, “I can’t wait until Joe gets back so we can do it together!”

The Real Housewives of New Jersey returns Sunday at 8 p.m. ET on Bravo.
