'I'm On My Deathbed!' Zach Roloff Suffers From 'Life-Threatening' Illness

Just weeks after losing their beloved dog Sully to cancer, Zach Roloff and his wife Tori were dealt another terrifying blow.

On last night's episode of Little People, Big World, the 26-year-old new father confessed to his family that he had secretly been suffering debilitating headaches and vomiting spells for months.

"I don't really talk about it because there's already so much happening," he told the cameras, referring to Tori's pregnancy, Sully's sudden death and possibly his parents' divorce and controversial new relationships. "Something's wrong, here. I don't know what it is, but it's something."

"Now would be a terrible time for me to have to go into surgery," Zach said. "Tori has already gone through enough. I don't want to frighten her."

The couple headed to the doctor, where tests proved inconclusive. He was ordered to keep a journal of symptoms to work on an eventual diagnosis.

Meanwhile, divorced pair Matt and Amy fought over where to hold son Jeremy and his expectant wife Audrey's gender reveal party on their Oregon farm.

When Amy refused to contribute to building Matt a bigger home on the property, he said he may not have much time left. Amy snapped.

"Don't give me this cruel, pity baby thing," she sneered. "Since I married you, you said you're dying. And I'm like, God, when's his time up?"

"That's downright mean," he responded.

Ultimately, Amy won the battle, and the family decided to hold the bash in her home.

She was relieved that Matt's assistant turned girlfriend, Caryn Chandler, 49, hadn't been asked to the party after she scored an invite to Zach and Tori's gender reveal gathering months earlier.
