Messer shares her twin daughters Aliannah and Aleeah, 15, with ex Corey Simms. She shares daughter Adalynn, 11, with ex Jeremy Calvert.
Speaking with PEOPLE about the new season of Teen Mom: The Next Chapter in May, Messer said "This has probably been one of the most difficult seasons for me."
"It definitely isn't the most difficult, but it was a very difficult season to film. Watching it at the end, I know it was all worth it, but it was very hard to navigate. I work on rebuilding a relationship with my father and then figuring out how to allow him and know when to allow him to build a relationship with Ali, Aleeah and Adalynn."
Messer's strained relationship with her dad has been documented throughout the show. The dedicated mom has always taken the twins and her youngest into consideration.
"I think that it was difficult for me to open up, but once I did, it allowed us all to rebuild," she said.
"I think this season, you also see all the talks I've had with my daughters over the years coming together, in a sense, and we see what they believe in and how they use their voices," Messer noted.
"You'll see why I had all those hard, maybe sometimes cringy conversations with them. I think it's opened the door for them to have any conversation with me now in their teenage years, which I think is vital."
