AceShowbiz - Former Food Network star Valerie Bertinelli recently experienced a terrifying anxiety attack, sharing her story in a vulnerable Instagram video that showed her hand shaking.

"I've sat on this post for a day because it's incredibly vulnerable," Bertinelli wrote in the caption. "But I'm posting because we're all out here doing our best having a human experience and none of us want to feel like we're alone in that."

Bertinelli described the attack as "really bad," explaining that she had not experienced one like it in a long time. "A few hours ago, I was weeping uncontrollably, and my heart felt like it was pounding out of my chest. I couldn't stop shaking," she wrote.

The "One Day at a Time" actress said that she takes anxiety attacks very seriously, knowing that her brain overthinks and catastrophizes, leading to a physical response over which she has no control. She uses meditation and EMDR therapy to calm herself down during attacks.

Bertinelli opened up about her attack to reach out to others who have experienced similar struggles. "Anyone else experience an extreme anxiety attack, and then the after effects still take a bit to calm?" she asked her followers. "Tell me I'm not the only one out here."

Many fans and celebrities, including Rosie O'Donnell, showed support for Bertinelli in the comments, sharing their own experiences with anxiety and reassuring her that she is not alone.

Bertinelli has been candid about her health struggles in the past, including her sobriety and a recent arm injury. She continues to inspire others by sharing her journey and promoting mental health awareness.
