As others have said, I would recommend going to therapy. But also, if you need to, quit. It might take a while to fix this issue but you don't need to be in continued pain while you're in it. This is a you problem. You're projecting how they perceive you based on your own insecurities instead of reality. It's a cognitive distortion. And unfortunately, if it's cropping up here it probably has cropped up before and will continue to crop up elsewhere. It took me a couple years in therapy and examining the same distortion cropping up in several different ways for it to sink in. But once I did - it changed how I perceive people. >I feel like the weird introvert This is probably not the first time you've felt that way. Maybe in high school you were in class and the loud talkative kids in class made jokes about you probably being a school shooter or whatever. Everybody has things they are insecure about. For me, it was feeling like people thought of me as a fat "neckbeard" nerd when I entered some social situations after years of seeing that stereotype mocked on the internet. The go to joke now for this archetype with Gen Z is "Discord mod" which I never wanted to be perceived as. For some, they might enter some situations feeling like people think they're a dumb hick because they have a slight accent. Or "These guys aren't taking me seriously, because I am a woman." The trouble is - sometimes it's true, right? Some workplaces are cliquey and toxic. Some people do think people with southern accents are less intelligent. So you have to look at reality as your source. Look for evidence. You've furnished no evidence they think that way of you. So where is this feeling coming from and why is it getting worse? It's not just that you feel like that, it's that you ruminate on it. But you've ruminated on it, it has magnified in your mind, and now you're losing sleep over it the night before. This can be a form of OCD. But I've had the experience with the right medication and talk therapy of improving. It's hard work but worth doing because distortions like this absolutely end up in scenarios like "I have to quit my job" and it gets to the point where it seriously starts affecting your life. I hope this helped. Just some of the stuff you've described resonated with me.
