That has been my experience with many (but not all) neurotypical people, most of whom had no reason to care about me. It's a little different if they're extended family or friends of family who try their best to care.

The most success I've had is chatting with other people who have autism/ADHD. It takes some practice to be both a listener and a speaker, but you can learn some cool things by pretending to be interested, and sometimes you'll find someone who is really interested i n what you have to say.

TL;DR: Talk to more people who share some interests / personality traits with you.
