Anna Duggar recently opened up about how she's been coping with her husband Josh Duggar's cheating scandal. In a new post on the Duggar family blog, the 27-year-old mother of four wrote that last year was extremely difficult, but she's relying on her faith to get her through.

“Many have asked how I am doing. So many have asked that it's actually humbling and touching. 2015 was the most difficult year of my life,” she posted Saturday. “Yet, amazingly I’ve found that in my own life crisis God has drawn near to me … and my faith has been more precious to me than ever before.” 

Anna also revealed she recently saw her husband in rehab and said that it was "an important step on a long difficult road." Josh, 27, has been at a faith-based facility in Illinois since August, after he admitted to having a porn addiction and being unfaithful to his wife. His apology came months after he admitted to molesting five underage girls, including some of his sisters, when he was a teen.

“I want to thank all of you for your prayers and your messages of hope," Anna continued. "I can never express how your kindness and prayers have brought encouragement when I needed it most — outpacing the grief and discouragement at every turn. I trust that God will continue to show His love and tenderness toward us and bring beauty from ashes — somehow — as only He can do. Please continue to pray for me, Josh and our children.”

Even though Anna gave fans a brief update on how she's been doing, the former "19 Kids & Counting" star stayed quiet about rumors she's pregnant with her and Josh's fifth child. Earlier this month, Life & Style reported that Anna announced that she thinks she's expecting again.

"She believes the baby is a sign that God has forgiven Josh for his many sins, and she’s vowed to stand by her husband," the outlet reported.

Last month during an episode of TLC's "Jill & Jessa: Counting On," Anna opened up about her and Josh's marriage and made it clear that she wasn't going to divorce her husband.

"In my heart, when I got married, I vowed to God first and then to Joshua, 'For better or for worse. 'Til death do we part,'" she said. "I pray that through all of this that I would be an extension of God's love to Joshua, that I would love him and forgive him and wait patiently and allow God to work through our hearts.”
