I coped by folding my arms tight across my chest and screwing a pissed-off expression onto my face. The grimacing, somewhat irritated expression that Autistic climate activist Greta Thunberg is now famous for20 is very similar to how I used to react to loud noise and social chaos. I had already started to cultivate a grumpy, goth persona to protect me from seeming weak. Instead of showing that I was overwhelmed, my mask told other people to stay far away.
