On March 15, "Teen Mom OG" stars Catelynn Lowell and her husband Tyler Baltierra both posted a series of bizarre tweets that left people worried and scratching their heads, but we now know what they were in reference to.

Catelynn has checked into rehab.

"Just let [fans] know that I'm just seeking help for my anxiety and depression at the moment," she told In Touch magazine.

If her social media is any indication, she will be getting treatment in Arizona.

"Arizona here I come...," she captioned an Instagram photo of an airplane on March 16. "I can't wait to be back to my normal self... this is for me and my family.. Novalee and Tyler I love you both very much!!!"

The couple had many fans befuddled after a string of unclear tweets that indicated that clearly something was wrong.

"Please just pray for my wife," Tyler tweeted on March 15, later adding, "For better or for worse...through sickness & in health...I will NEVER stop fighting for my wife. Keep her in your prayers...thank you."

If that wasn't vague enough, Catelynn also went to social media to give a strange description of her state of mind, and it doesn't exactly offer hope.

"For everyone that thinks I'm so 'strong' I'm really not...one day you will know why," she wrote. "I also can be very weak."

She then thanked her fans.

"You guys have NO CLUE on how much you lift me up sometimes…," she told her nearly 1.2 million followers.

It's been thoroughly documented in the past that Catelynn struggles with depression and she even contemplated suicide before.

Things certainly seemed to be going better for both Catelynn and Tyler last year as they tied the knot in a fairy tale-inspired wedding in Michigan.

The nuptials were certainly a long time coming for Catelynn and Tyler, who had dated since they were both in seventh grade.

The couple welcomed baby Nova Reign on Jan. 1, 2015. It's their second child, but they gave up their first child for adoption. The duo welcomed a daughter, Carly, in 2009 when they were teenagers. But, the pair made the difficult decision to give her up for adoption.

Many Twitter-haters criticized the duo's decision to keep their second child, but Tyler fought back.

"So sick of the ignorance in the world," he tweeted on Jan. 3. "Just because you place a child for adoption doesn't mean [you're] not allowed to have another #GetReal."

Things didn't get easier for Catelynn after the birth though, as she said she suffered from postpartum depression.

"I just need encouragement. It's good to have somebody to push you to do something because those are the last things you want to do when you are going through it. You don't want to get dressed. You don't want to get out of bed. I wanna just sleep my life away," she told her husband on "Teen Mom."

"I don't want to deal with that forever," she continued. "That's not what I want to deal with for the rest of my life. I don't want to be like that. I don't want Nova growing up seeing me go through, like, spouts and stuff."
