It's been a tough time for Amber Portwood.

The Teen Mom star took to Instagram on Tuesday and shared a cryptic post about her personal pain.

"I am so heartbroken right now…omg?" she wrote alongside an image of a shattered heart.

She also received some support from her fellow MTV moms. "I love you so much," Catelynn Lowell wrote in the comments section. "See [you] tomorrow."

"Keep your head up!" read a comment from the Coffee Convos podcast, which is hosted by her co-star Kailyn Lowry and Lindsie Chrisley. "'This too shall pass.'"

Portwood didn't specifically state what caused her heartbreak. However, her post came hours after Radar Online published a report claiming her boyfriend, Andrew Glennon, started texting another woman after Portwood's domestic battery arrest.

"Amber's post was in direct response to the Radar story," an insider told E! News. "She saw it and reacted. She has had trust issues with Andrew on a few fronts. This is just one of them."
