Catelynn Lowell

For much of the past two years, Catelynn Lowell's struggle with mental illness has been documented by Teen Mom OG camera crews.

Lowell has been commended for her bravery in being so honest about her difficulties, and many have heaped praise on her husband, Tyler Baltierra, for his endless support of his struggling wife.

As expected, last night's Teen Mom OG reunion show was loaded with drama, much of it having to do with ongoing questions about Ryan Edwards' sobriety.

But while Ryan's situation may have dominated the tabloid headlines in recent weeks, he's certainly not the only member of the TMOG cast to grapple with personal demons this season.

In the wake of being slammed for going back to rehab, Teen Mom OG star Catelynn Lowell is clapping back at her haters.

She's being mom-shamed, wife-shamed, and plain ol' shamed for "abandoning" her family. And she's clapping back.

Over the course of the past 18 months, Catelynn Lowell has checked into rehab three times.

Sadly, she's taken a fair bit of flak from insensitive fans as a result of her struggles with mental illness.

On Twitter, Catelynn Lowell has been celebrating her sobriety. She says that she's been sober for months, now.

But on Teen Mom OG, which is filmed earlier, she's still in the process of explaining to her husband why she needs to go to rehab in the first place.

Last night on Teen Mom OG Season 5 Episode 18, the season finale, Maci Bookout learned that her ex, Ryan Edwards, is expecting.

She discovered this only through their son Bentley, however, and that wasn't even the biggest Edwards bombshell to come.

Catelynn Lowell has made no secret of her struggles with mental illness and addiction in recent years.

While critics have called Catelynn a drug addict and attempted to stigmatize her battle with PTSD, the Teen Mom OG star has continued to serve as a reminder that those who face their demons should be applauded, not condemned.

Catelynn Lowell and Tyler Baltierra have had quite a year.

There may have been more ups and downs in the past 12 months, but the beloved Teen Mom OG couple deserves praise for consistently turning negatives into positives.

Last week, Catelynn Lowell and Tyler Baltierra appeared on Kailyn Lowry's Coffee Convos podcast for a surprisingly candid interview that touched on a wide range of topics.

The portions in which Catelynn and Tyler discussed their desire to have another baby rightfully received the most attention, but there were plenty of gems hidden throughout the episode.
