"The holidays have been a roller-coaster for my bride," Rory Feek writes in his latest blog post, rehashing the season's ups and downs with his terminally ill wife, Joey Feek.

"They say at Christmas time emotions run high, and you feel more than you do the rest of the year," Joey wrote on Tuesday. "I think that's probably true. Though she managed a smile most of the time, Joey's heart was heavy and she was feeling some things she hadn't before... A sadness. A fear of the unknown. And even some anger -- not at God, just at her situation I suppose. It's not easy for her to be as excited about what the new year holds in store as it was last year."

In October 2015, the couple announced that Joey would no longer be undergoing treatment for her terminal cancer. By November, the 40-year-old singer had entered hospice care.

In a previous blog post, Rory wrote about the "amazing day" they shared with family on Christmas: "There was a beautiful Christmas tree filled with wonder, Christmas cookies that we made together, new pajamas that we opened and put on the night before (it’s our yearly tradition), lots of presents to open on Christmas morning, and a big Christmas dinner in the evening and fun with all of Joey's family."

In his latest update, Rory opens up about the support he and Joey have received from their neighbors, gospel songwriters Bill and Gloria Gaither.

"Bill comes to see Joey just about every day, when he's not on the road," Rory writes. "I think he just wants to brighten Joey's day and create as much joy for her as he can. We all do."

Rory shares that the couple's upcoming Hymns album, which will be released next month, was produced with the Gaither organization.

"For each project, Bill has personally sat down and interviewed us on-camera and asked us questions about the music we’ve made and about our lives," Rory writes. "But what he's actually doing in those moments is wrapping his arms around us, and doing all he can to shine a light on us for the world to see."
