On Thursday, the CDC released new data showing that almost 15.5 million U.S. adults are living with ADHD. More than half of those individuals received their diagnosis in adulthood. That includes me. The diagnosis came as a relief and validation — a way to understand years of impulsivity, inattention, and struggles with daily life. I was diagnosed at age 36, after first one, then two, and ultimately, four of my five children were also diagnosed with ADHD.
