Rob "Sleepwalker" Weisberg never intended to become an author. In fact, if you had asked him years ago whether he saw himself writing a book, the answer would have been a definite no. But life has a way of charting its own course, and for Weisberg, a firefighter, 9/11 survivor, and long-distance hiker, that course led him to pen a powerful memoir: From the Grey Tunnel to the Green Tunnel: A 9/11 Firefighter’s Journey from Despair to Hope.

The book is a powerful memoir of survival and resilience. It delves deep into his experience as a first responder during one of America’s darkest days, his long battle with PTSD, and his extraordinary journey along the Appalachian Trail (AT), where he found healing and a renewed sense of purpose.

For many, September 11, 2001, is a moment in history that left an indelible mark on the world. For Rob Weisberg, it was personal. He wasn’t just watching the horror unfold on television—he was there as a firefighter who responded instinctively to the chaos at Ground Zero, as the Twin Towers fell and left fighting for his own survival.

The memories of that day are etched into his mind: the deafening roar of the collapsing buildings, the thick dust cloud that turned Lower Manhattan into a suffocating, gray abyss, the helplessness of watching people leap from the towers, and the desperate attempts to save lives in the midst of unimaginable destruction. While he walked away from Ground Zero physically intact, the emotional and psychological scars ran deep.

For months after the attacks, he was involved in the rescue and recovery efforts. But as the physical wreckage cleared, the wreckage within him remained. Like many first responders, he developed (PTSD), an invisible but relentless affliction that seeps into every aspect of life. The nightmares, the simmering anger, the hair-trigger reactions—these became his new reality. And like so many others in his position, he tried to suppress it, believing that seeking help was a sign of weakness.

The weight of PTSD was unbearable. Weisberg’s relationships suffered, his mental health deteriorated, and he found himself at a crossroads. Then, in 2023, he made a bold decision—he would hike the Appalachian Trail. This wasn’t just an outdoor adventure; it was a lifeline.

The Appalachian Trail, often referred to as the "Green Tunnel" due to its lush canopy of trees, stretches over 2,000 miles from Georgia to Maine. For Weisberg, it was the antithesis of the “Grey Tunnel” of 9/11—the suffocating dust and devastation that had engulfed his world.

What started as a means to escape his pain turned into a profound journey of self-reflection. “I realized the hike was working its magic when, for the first time in a long time, I cared about my safety,” he shares. Before the trail, suicidal thoughts had haunted him. But out in the wilderness, with each step forward, he found himself reclaiming the will to live.

The AT wasn’t just a test of endurance—it was therapy. The solitude, the physical challenge, and the camaraderie among fellow hikers all played a role in his healing. He found peace in the rhythm of walking, comfort in nature’s embrace, and clarity in the silence. By the time he finished, he was not the same man who had set foot on the trail months earlier.

Encouraged by friends, family, and even strangers who followed his journey, Weisberg decided to share his story. Writing From the Grey Tunnel to the Green Tunnel was no easy task. Reliving the trauma of 9/11, dissecting the darkest corners of his mind, and putting those experiences into words was emotionally exhausting. The chapter on 9/11, in particular, was especially draining—he had to take breaks, stepping away when the memories became too overwhelming.

Yet, despite the difficulty, he knew this book needed to exist. Not just for him, but for anyone battling PTSD, for first responders who suffer in silence, and for those who need to know that healing is possible.

Weisberg explains. “If I wasn’t candid, the book wouldn’t be effective. People suffering from PTSD need to see themselves in my story. They need to know they’re not alone, that it’s okay to ask for help.”

At its core, From the Grey Tunnel to the Green Tunnel is about perseverance. It’s about not giving up, even when every fiber of your being wants to. Weisberg’s message to readers is simple yet powerful: “Don’t quit. Stay in the fight.”

Mental health struggles can make suicide seem like an escape. Weisberg understands that firsthand. But his book aims to show that while the road to healing is long and arduous, it is worth walking. Just like the Appalachian Trail, life’s journey is filled with obstacles, but also breathtaking moments of clarity and beauty.

He hopes his story will encourage others—whether they’re veterans, first responders, or anyone grappling with trauma—to seek help, talk about their pain, and find their own “Green Tunnel.”

For Weisberg, the journey doesn’t end with the book. He plans to continue advocating for mental health awareness, sharing his story through speaking engagements, and supporting initiatives that provide aid to first responders and veterans battling PTSD.

If there’s one thing readers should take away from his book, it’s this: The past may shape you, but it doesn’t have to define you. There is always a way forward.

And sometimes, that way forward is just one step at a time.
