'Teen Mom' Stars and Their Kids

She also express frustrations with her ex and his wife for not keeping her in the loop.

As someone who has experienced panic attacks and struggled with anxiety for years, it was a hard pill for Amber Portwood to swallow when she learned her daughter, Leah, may be following in her footsteps on Monday's "Teen Mom".

Though Portwood said coparenting with ex Gary Shirley and his wife Kristina had been going "well," that wasn't the case by the episode's end after she found out they had been keeping information from her regarding Leah's mental health.

In a scene between Kristina and Gary, Shirley's wife said she got a text from someone at Leah's school saying the 10-year-old "started crying and saying her chest hurt" and noted it wasn't the first time she's experienced something like that.

Though Kristina was worried she was having a panic attack, Gary didn't want to accept that as an option. "If it gets worse, we can look for some help," he added.

Kristina eventually filled in Amber when the two took Leah to get a pedicure together. "I guess her chest got tight and she couldn't hardly breathe and she was crying," said Kristina."

"How is it a panic attack?" asked Leah, who then said she'd had "eight maybe in the past couple years."

"Why wasn't I told this?" Portwood asked Kristina after hearing the news. "I feel like you guys aren't telling me anything right now. We need to figure that one out. When things like that happen, I really would love to know."

After Kristina said she promised to keep her updated in the future, Portwood explained that she also started getting panic attacks when she was Leah's age. "It's real," she added, "F--k my life. I just feel like crying."

And when Amber got home, that's exactly what she did. "I'm completely crushed that Leah might be having panic attacks," she said in a confessional, before getting emotional as she spoke to boyfriend Andrew Glennon about the situation.

"I feel like, when something like that happens, you should just let the mom know," she said through tears. "I told [Leah] next time it happens, call me. There's things you can do to get your mind off it. She doesn't know yet. She said it was like her eighth one."

Even Glennon was surprised the couple had "[cut] out the best coach" Leah could have, as Amber noted she felt "so out of the loop and it sucks so bad." She added that she remembered "how horrible it was" for her as a kid, breaking down as she said she was sad Leah was having panic attacks, period.

Over at Gary's home, Kristina filled her husband in on Amber's concerns. "It might not be, we don't know," said Gary, who said the only "stuff she battles is boyfriend stuff, little tweeny drama."

While Kristina rolled her eyes, Gary expressed more doubt Leah was having panic attacks.

"Leah's in very good hands. I don't know everything Amber has, I don't understand it. I know there's bi-polarness, I don't want Amber to say, 'I think Leah has this because I have this,'" he continued. "There's no cause for concern for any psychiatric help. I don't want to put Leah in that category, I want Leah to be her own person and not be shadowed by something her mother has."

"Teen Mom OG" airs Mondays on MTV.
