DALLAS -- As Iraq War veteran Randy Shack prepares to head to the driving range at Cedar Crest golf course, he remembers how he felt just a few months ago.
"It was just so much anxiety, because I'm a big hermit," said the Rockwall resident.
It was a reluctant return, but Shack's wife was clued in.
"She knows I like golf," Shack said.
And when he would hover on golf events -- even though his wife would implore him to change the TV channel -- it was a dead giveaway.
And thanks to a gentle push out the door, he's back on the course and back in the game.
"Yeah, I love it," he said. "It's just so peaceful."
Shack's new normal the result of his service in the Iraq War as an Army rifleman. The retired corporal lived through multiple improvised-explosive blasts, suffering spinal damage and requiring him to use a wheelchair.
His service also makes a question about second chances tough to handle.
Shack fought back tears saying, "[You] Kinda [feel like] you don't deserve it, almost. Other people should have got second chances."
He then wiped a tear from his eye.
This spring, Cedar Crest Golf Course hosted PGA Hope, a program aimed at helping veterans improve their mental, social, and emotional well-being.
"It was good to see them light up," said Cedar Crest Assistant Golf Professional Maulana Dotch. "They're hitting good shots, laughing, joking with each other."
At his wife's urging, Shack joined the program, and eventually began using a modified golf cart called a solo rider. It has a chair that swivels, allowing him to make better swings at the golf ball.
"You get that comraderie going, talking about this and that," Shack said of the PGA Hope program.
Then came Shack's golf moment that went national. He made SportsCenter's Top 10 countdown with at dificult birdie putt at a PGA Hope tournament.
"My friends were telling me on Facebook, 'Hey, you're on ESPN.' And then they showed me and I'm like, 'Oh man, that's so crazy," Shack said.
After sinking the putt that went national, Shack exclaimed, "It can be done!"
Yes it can. And he serves a living proof and inspiration.
