At this point, if you follow Teen Mom gossip even the tiniest little bit, you're familiar with Catelynn Lowell's recent mental health woes.
She's struggled with anxiety for several years, and things got worse when she gave birth to her daughter Nova three years ago.
She had a particularly bad case of postpartum depression that she's still dealing with, she suffers from panic attacks, and she just revealed that she was also recently diagnosed with PTSD.
Last fall, she and Tyler learned they were expecting another child, but then she had a miscarriage, and it affected both of them deeply.
It was so hard on Catelynn that she began having suicidal thoughts, and so made the decision to check herself into a treatment center to get a handle on things.
She spent several weeks there, and a few weeks after completing her treatment, she went back for another round because she still didn't feel well.
Right now, she's been home for nearly a month, and it seems like she's doing well.
But as always, Teen Mom OG is a bit behind real life, so we're just now seeing the beginning of Cate's stay in rehab.
And as we see in this sneak peek for the upcoming episode, she definitely dealt with some rough issues there.
In the clip, Catelynn receives a visit from Tyler, Nova, and Maci Bookout, which is really nice to see -- we knew they were close, but not close enough for Maci to fly across the country to see her!
Catelynn gives out some hugs, and then they all sit down for a little chat.
After Cate asks Maci about her flight and remarks about Taylor staying home with all three kids, Maci asks her what she's been doing during her treatment.
"Tons of therapy," she answers, "and group therapy, trauma classes. It's been really good though, honestly."
We can believe her -- it does look like she's feeling better already.
"So what was going on?" Maci asks next. "Anything happen, just life?"
"Well, no, really," Catelynn tells her. "Me and Tyler actually got pregnant and I had a miscarriage."
Here's where it gets extra rough, because as we learned earlier in the season, Maci and Taylor had a miscarriage recently as well.
She tells Catelynn that, and it's really just a very sad moment.
Cate tells her that she's sorry, and Maci says that they haven't told anyone about it yet.
"I think it's another one of those things that makes it ... it doesn't make the pain easier, it just makes the experience easier, to talk about it," Maci says.
"It doesn't help anybody to pretend that it didn't happen, or that that baby didn't exist."
Tyler, who's been looking so sad during the entire conversation, adds "it may not have been a fully developed baby in the womb, but it was in our hearts."
