Is AUTHOR wrong in the post ? POST : *TL;DR: I can get annoying from the intensity of my interests and how much I talk about them, I got put in my place, but felt attacked and don't know if that's a reasonable reaction or what to do about it.* 

This is a pretty small issue, but here goes.

I have a group of good friends ranging in age from older teen to young adult. We have a couple group chats (various circles of people) that we chat on. My friends and I have ADHD and/or autism, which means we struggle with social cues and sarcasm. We also tend to get really, *really* into things and talk about them a lot. It can be difficult to shut up, but I try and I at least make sure that other, especially less assertive, people have space to talk too. We also all have anxiety. All of us are aware of each other's quirks and struggles and are supportive.

I really like my original characters, and I talk about them a lot. Like, a *lot*. But they get why I'm so interested and they love to discuss their own characters with me and we go back and forth. My friends jokingly hate two of my characters because they're villains, and they make fun of me sometimes because I defend the characters and my love for them. This is almost always funny for everyone involved and it's a nonissue.

Yesterday, I compared one of my characters to a different, video game, character that they really like. This offended my friends (longer story, but yeah it was insulting, I get why they're unhappy) and they started teasing me and making memes about my mistake and about me being so obsessed with the character that I can't not reference him everywhere. When I got embarrassed and asked them to stop, they just posted the memes in a different chat so more people can see. I don't think they realized I was serious, I didn't make it super clear (again, we suck at social cues) and that's my own fault. They've talked about unrelated stuff since, I felt too ashamed to participate. I left one of the chats this happened in and am considering leaving the others until I'm less embarrassed and until the jokes are buried under more conversations. I'll come back later, try a lot harder to stop referencing this interest, because this is deffo not friendship-ending material and they like me otherwise. It feels so childish to be upset over something so small and even more childish to ask them to stop because I'm taking this way too seriously...

AITA for being so upset about this, and for leaving? How should I fix this?
