I was, too, was bullied in primary school, however, I tried to be more 'normal' at secondary school. I then came across as incredibly shy and nerdy (I had 1 friend and spent most of my time reading). In the last year or so, I started to 'be myself' more, so to speak. Meaning, I stim in public more and make less of an effort to stop it.
People comment on in, and perhaps they are teasing me but I don't react as they would like me to (either I ignore them, or laugh with them). So, yes, people do tease me from time to time, but I interpret it as good natured because... well, I don't really care what most of them think. I care about what my friends think, but some random person? Not so much.
