So you were just diagnosed with attention-deficit/hyperactivity disorder. You're probably half-relieved-half-worried. All those doubts and wonders that you had are finally answered. Your thoughts might be like "This revelation explains so much about myself! Now life is going to be easy!"

Will people accept me for who I really am?"
