Stage 3, probably. To most appearances, I am a very introverted, very awkward (physically, too) teenage girl with set hobbies (they see me reading, mostly) and difficulty mixing with people my age, but I am not a complete weirdo like I was to my peers when I was younger. Then, I suppressed the weirdness, but that often led to me tripping up on all the rules and stuff. Now I can deal with them better, I understand the theory behind them more. If you don't know me, I'm just the NT geek who somehow manages to have unwanted company. If you interact with me, you can see I'm not all 'there', but I'm still a lot better than I was (I should hope so!).
When I was younger I was obsessed with being normal (and no, I won't put that in quote marks), so I probably looked more normal to adults then than I do now because I suppressed lots of things. I didn't stim (at least, I became very aware of myself and stopped whenever I caught myself), was just very lively and animated, asked too many questions all the time, but it was the other kids thought I was just weird, so I was stage 2 then. But when I was 10 I withdrew...started having mini meltdowns at other people's houses, everything got a little too much and I spent more time than ever by myself in my room.
Argh confused post. I'm tired! At 9pm, haha.
