Matt Klein thought he was dealing with depression. After a job change and the arrival of a new baby, he found himself in a fog. Listless. Unmotivated. And vaguely “off.” He just didn’t want to do anything. His wife noticed the shift, too. But the depression diagnosis never fully explained it. It wasn’t until he was evaluated as an adult that inattentive ADHD and slow processing speed brought his story into focus. Matt, a software engineer, shares a story about a door that hung slightly askew — and how intensely it bothered him. He couldn’t stop thinking about it. That crooked door became a metaphor for his experience with undiagnosed ADHD: the mental friction, the fixation, the sense that something was out of alignment.
