What is something your undiagnosed ADHD cost you?

For me it would be a romantic life. I’m 25 years old and was finally diagnosed last year. I never dated while growing up as I always felt like I was never enough, (internalised ableism). Now that I have a diagnosis and finally understand myself, I now get why I always felt that way. Nonetheless, I feel like I’ve lost the window of time for formative romantic experiences that people are supposed to have while they’re young. What is something your undiagnosed ADHD cost you?
