I hear people without ADHD say this. I didn’t every associate thus with ADHD.

I gather most people don’t imagine themselves internally to be an old person. Lots of old folks say this

I remember my dad talking about conversations he had with my grandma saying she felt like she was still young.

Due to my job I end up working working with kids half my age and I still don’t feel like an adult.

I don’t think anyone ever truly feels like they’ve grown up and we’re all just pretending.
