ADHD is a thing. Every brain is different.

Think about it like this: depression is real. Everyone can feel a bit "depressed" sometimes or grieve after experiencing emotional hardships, but that doesn't mean depression isn't real.

Also much like depression doesn't simply manifest in being sad all the time, ADHD doesn't simply manifest in being distracted all the time. I've heard ADHD described as an inability to control what your brain focuses on rather than a lack of focus, but it can vary between persons.

As to whether you in particular actually "have ADHD" (i.e. meet the formal diagnostic criteria of the DSM condition by that name) that's between you and your therapist to decide.
