More: Walter is my hero, and I truly believe he and I were meant to find one another. I adopted him at 7 years old, exactly 7 years after I was diagnosed with clinical Post-Traumatic Stress Disorder. I had always hoped someone would come along and help me after my diagnosis, and although it took us a little while, Walter and I found each other eventually. He is my best friend and has changed my life in more ways than I can ever fully describe.
