The '19 Kids and Counting' stars are gearing up for their return to the small screen.
In the first promo for their TLC show, Jill and Jessa: Counting On, the Duggar sisters look back on the hard times their family has endured this year.
This will be Jill (Duggar) Dillard and Jessa (Duggar) Seewald's first return to reality television since their brother, Josh Duggar, admitted to molesting underage girls, including both sisters, when he was a teenager. Months later, it was also revealed that he had two accounts on Ashley Madison, a dating site that helps married people cheat on their spouses.

Jill broke down recalling what the Duggars have been through. "You're angry and hurt and all those emotions all mixed together," she admits. "I cry a lot of tears, I still do. I know I'm hurting."
That being said, the sisters remain optimistic and are "excited for what the future holds."

Prior to landing the new reality series, Jill and Jessa appeared on the TLC documentary, Breaking the Silence, which focused on sexual abuse.
The family has been slow to forgive Josh in the wake of all the revelations. In September, Jessa took a stand against her brother by sharing a Facebook post written by her father-in-law, Michael Seewald, in which he called Josh a "hypocritical Christian" after news broke of his Ashley Madison accounts.
