When you’re intelligent and do well in school, it’s easy for clinicians who don’t understand ADHD fully to dismiss the possibility. However, you can do well in school and still have ADHD. Probably not severe ADHD, but ADHD nonetheless.

As someone with significant social anxiety myself, I know it can take over your life and be so apparent on the surface that it can hide many other things.
