What would you do if the happiest memories of your life vanished? That's what happened to Sgt. Lisa Crutch, a soldier who manned machine guns in Iraq.

She was treated for her visible injuries but didn't realize she'd sustained a traumatic brain injury. Inside Edition teamed up with Wounded Warrior Project to learn why Crutch credits the organization's services with helping her heal.
