'I Can't Do This!' Catelynn Lowell & Tyler Baltierra's Marital Issues CAUGHT On Camera

Tyler Baltierra isn't having an easy time coping with Catelynn Lowell's battles.

In an official teaser for upcoming episodes of Teen Mom OG season 6, things get very heated and emotional between the couple. Cate returned home from a rehab center where she received treatment for her mental illness for a month.

As seen on the show, things have been difficult for Tyler as he helps his wife cope with rebuilding herself after returning home. In the teaser he tells her, "I just don't want any resentment to be built." Footage of Cate laying down covered in a blanket was playing as he is overheard saying, "This is probably the hardest year that we've had in a long time."

Breaking down in tears, she admits, "I feel like my mental illness ruins everything." Tyler fires at her, "I can't do this forever."

During a heartbreaking therapy session, Novalee's mother says, "It's like my life would be so much better if I wasn't around."
