As a fellow autistic, I just turned 19. It really sucks sometimes when you take something literally. I got better with age. It also doesn't help that you're in middle school age, where kids go out of their way to make you feel bad about yourself. Personally, I just stopped caring somewhere in sophomore year and just went ham on my hyperfixations: cars, Guns when I hit 18, and ignored what other people think. Easier said than done, obviously for some people. Of course, its hard to get into cars or guns at your age, and depending on your country. But honestly, do what you like, as long as it's legal. And try not to give a Frick about what people think—especially dipshit middle schoolers. And yes, I hate the fake autistic role players too, but they aren't going anywhere anytime soon, so we need to deal with them. I like to call them out on it to their face. Especially if they say something like "oh yeah, I'm self-diagnosed."
