Anna Duggar opens up on husband Josh's scandal

The Duggar family is returning to TV with a full season of "Jill and Jessa: Counting On." The show originally started as a three-part special, but it will return as a series starting on March 15 on TLC.

In a promo clip on People's website, Anna Duggar, wife of Josh Duggar -- who fell from grace after he was embroiled in child molestation and Ashley Madison scandals -- opened up about life after learning about her husband's problems.

"I don't know what I'm stepping into," she says in the video. "I don't know how to handle each situation. It's not anything I ever would have thought I would walk through. [I tell myself,] 'Just do the next right thing, have the next right response for the next 15 minutes.'"

Meanwhile, Jessa Seewald and her husband Ben are figuring out life as first-time parents of their son, Spurgeon. "Having the full 24-hour care of an infant -- every diaper change, every feeding, it's all on you," Jessa says in the clip.

The show also follows Jessa's sister, Jill Dillard, and her husband, Derick Dillard, as they work as missionaries in Central America along with their baby son, Israel.
