FORT MYERS, Fla. - Walking slowly, but surely, down the halls of Golisano Children's Hospital, Zachary Latawiec is nothing short of a miracle.

"I'm fine with it. I was just surprised I got struck," said Zac.

Struck by lightning 15 days ago on Fort Myers Beach, doctors didn't think he'd make it.

"He had a heartbeat, but he was not breathing. And the heartbeat was not effective to keep his organs alive," said Doctor Roberto Monge, of Golisano Children's Hospital.

They say the bolt sent an electrical current through his body.

"We assumed there was going to be some brain damage," said Dr. Monge.

But one week later, Zac opened his eyes.

The day after that, he spoke, telling his mom he loved her.

"Overwhelmed. Overwhelmed. Just have to thank all the doctors here. It's just overwhelming," said Danita Lovins.

Although it's still difficult for Zach to talk loudly, or for a long period of time, his courage and determination to get better, speaks for itself.

"It was hard for me to walk for a while, but then I just got up and started walking now," said Zac.

"He's a tough kid. He's just tough. He's a fighter," said his mom.

Zac doesn't remember what happened that day.

"I just remember going to the beach and getting there. That's all."

"What he remembers next, is waking up at the hospital."

Soon he learned his girlfriend, Chelsea Gill, was also struck. She survived, and has been by his side since.

"Before we had a strong connection, but now we have an even stronger connection," said Zac.

Chelsea's uncle, Scott Wilcox, died instantly.

Doctors say Chelsea's 911 call for help, saved his life, as well as the CPR witnesses started right away.

Soon, Zac could be going home, but he will still need physical therapy for muscle weakness and a fractured clavicle.

"Little by little, we will take it day by day," said Danita.

When asked if he thought he was a miracle? He said yes. And he will continue his motto of staying strong, staying positive. He also said, he'd be back to the beach.

"I'm just not scared," said Zac.
