Washington DC meet up?

Hey. I have a big group of friends in DC- Huge social group. But I’m feeling completely misunderstood and like I don’t fit in. I feel like people don’t get the niche topics that I’m interested in (and therefore have lots of information to share) ~ how do you find people that understand you? I feel like all I can do is call my dad 😬 I feel behind socially and it’s odd because I come off 100% as an extrovert. Any advice? Anyone want to meet up in DC?
