Quote from : Until Tuesday: A Wounded Warrior and the Golden Retriever Who Saved Him Book

[it] isn't something you just get over. You don't go back to being who you were. It's more like a snow globe. War shakes you up, and suddenly all those pieces of your life - muscles, bones, thoughts, beliefs, relationships, even your dreams - are floating in the air out of your grip. They'll come down. I'm here to tell you that, with hard work, you'll recover. But they'll never come down where they once were. You're a changed person after combat. Not better or worse, just different.
