Mark Wills has joined forces with USA Cares -- a non-profit national military assistance charity designed to assist those affected after the 9/11 tragedy -- to launch the 'Crazy Being Home' campaign, bringing awareness to those suffering from Post Traumatic Stress Disorder (PTSD) and traumatic brain injury (TBI).

Wills will be the official spokesman of the military outreach program and will perform at the 6th Annual National MilBlog Conference in Washington D.C. on Friday (April 29).

"We're honored that Mark would take time out of his busy schedule to perform," says Andi Hurley, founder of the National MilBlog Conference in Washington D.C. "Mark's tireless support of the military community makes him a perfect fit."

The partnership between Wills and USA Cares started after the singer recorded a new tune, also titled 'Crazy Being Home,' which will appear on his forthcoming album, 'Looking for America.' The song, which was written by the Warren Brothers (Brett and Brad), along with Chris and Robin Lindsey, will be the anthem for the campaign Wills holds very close to his heart.

"I was moved to record this song by a young man who is on active duty with the special forces," says Wills. "His story and reaction inspired me in such a way that we hope it serves as a message to speak to all of our veterans to say 'you are not alone.' Suffering with PTSD is an injury of war and the Warrior Treatment Today 'Crazy Being Home' efforts are to open the door to make emotional and physical therapy available to anyone and everyone who suffers."

Wills knows all too well what kinds of effects loved ones face after those close to them are sent home from war, as his father suffered disabling psychological symptoms after serving in the Vietnam War.

"When my dad returned, he was inexplicably a changed man," Wills says. "The problem was we didn't know what it was or what to do for him. Now we know he was suffering from PTSD. It's sad that even still today, too many men and women who sacrificed their lives go without diagnosis, help or treatment. We're hoping to change that."

Wills' latest single, 'Looking for America,' is available for download through iTunes. 'Looking for America,' the album, will hit stores June 21.
