The David Lynch Foundation's Operation Warrior Wellness program.

"The first week I was there three soldiers got killed there....I was certain I wasn't going to make it back home and I started thinking about suicide. I felt I was going to die anyway, so why be miserable day after day when it's going to happen? I was just certain it was going to happen....I tried five or six different kinds of depression medicine, two or three different kinds of anxiety medicines. When I continued to try and try and try and things weren't helping, hopelessness really was taking over and I still continued to think almost daily that suicide was going to be the option."

In 2011, Luke Jensen learned the Transcendental Meditation (TM) technique - a stress reducing practice, proven to combat the effects of PTSD.

"For the first time in I don't know how long I felt hope....I don't take anxiety medicine at all anymore....It's made me a better father, a better husband. I'd consistently thought about suicide before I learned TM. It was the first thing to kind of get that away and get that off my mind. It changed everything."
