Catelynn had a tough time reconciling the imminent separation from her family when she took some much-needed time for herself at a treatment facility. But during tonight's Teen Mom OG episode, the young mother happily rejoined her husband Tyler and daughter Novalee after completing her lengthy stay and leaving with a new outlook.

But looking back on her departure from the Arizona-based facility, how did Catelynn feel closing this chapter?

"I remember before going home being excited to reunite with my family, but also nervous and anxious," the 25-year-old reveals in the clip above. "It's different -- you have so much structure, and all of these things going on around you 24-7. And then you go out and there's nothing. It's like, 'Whoa, this is weird.'"

What valuable lessons did Catelynn learn from this experience? Hear her open up in the video, and be sure to keep watching her journey every Monday on TMOG at 9/8c.
