Impulsive. Frustrated. Unmotivated. Sad. Discouraged. Dejected. A failure. This is how I described myself as a child and teen, before I was diagnosed with ADHD, at age 19. To know, finally, that there was a cause for the symptoms I had struggled with for so long was comforting. Knowing the “why” led to treatment, which led to the “how” I would accomplish my goal of being a nurse. Happy, successful, determined, ambitious, goal-oriented, calm, and clear — these words describe me today, as an adult with ADHD.
