That's how I felt with autism for sure. Not formally diagnosed but to go "oh most people actually naturally and subconsciously are aware of other peoples micro expressions and do not have to conciously decide to "turn on" that part of themselves when talking to other people" and explaining some of the biggest hurdles of my developmental life was a huge relief.
Like I was getting pretty misanthropic for a bit because 1 I was getting bullied by kids and adults alike for not "just getting it" and 2 thinking most people consciously sat down and choose to be jerks and inconsiderate.
I was accused of plagerism 3 times on big projects in school because "there is no way you wrote this level of work". The first time I only "got a way with it" because as he read more the teacher realized that these werent paragraphs but instead multiline run on sentences.
Once I got better at that though I actually failed those classes because they could believe it (made up for them quick no sweat off my back now). I really felt like "damn thanks but please can I just keep a passing grade instead".
