I did not know until very recently I had Asperger's so I always thought I was just weird as hell and that the way I acted naturally was wrong... over time I trained myself to be what I thought would make me seem normal. It was a long, terrible and crushing phase of self-denial - I really think it stopped me from growing as an individual (through that period of my life) and reaching anything near my potential.
I still hold on to many of these habits, they have made up most of my life so they are not easy to shake.
In recent years though, still before realising I has Asperger's I decided to make a kind of shift - I noticed trying to act the way I thought people wanted me to was incredibly taxing... and that for most people if I let the mask slip and acted the way I wanted to, it became strange and taxing for them... but whereas me restricting myself made me closed-in and miserable and restricted my creativity, me letting go and being weird seemed to open other people up, break through social pretense to a degree and inspire creative thought in them!
Even when it goes wrong and they just find it awkward and get tense, at least you can put that on them instead of on yourself. I don't mean that in a selfish way, giving many people each one passing awkward moment is less terrible overall than yourself enduring the tension in every social interaction.
After I realised this and embraced the weird, and feeling like an alien I began to make a joke of it - I would greet strangers by saying "greetings!" (in my mind it was more like greetings, earthling!
). And what I noticed was... if you start a conversation with a stranger (not something I often do mind you, but I experimented with it) by saying hi, the conversation would drift to the same boring topics I hated discussing. The weather, sports, people's job or school... small talk. But if I said "greetings stranger" it would almost disarm that reflex in them and we would go on to discuss our opinions on things or more abstract concepts and ideas more often.
What I'm trying to say here is, the cost of trying to meet people's expectations for me has been huge, and not a cost worth paying... and conversely the reward for choosing challenge those expectations has also been great in it's own way! Give people a fresh perspective! I do still try and tone myself down but I try and limit it as much as I can to just the things I should do to be courteous, I tend to have conversations that should be had quietly in an inappropriately loud voice and tap my feet and hands annoyingly as a stim, so I try to remember to be a little quieter when it's important and stim by rubbing my fingertips together or something less annoying to the average person when in public.
Embrace the weird! Many people find it quite refreshing!
Thank you for your fresh perspective! Very interesting and hits very close to home.
Because of my negative reactions to "being myself" in the past, I've created a mask that is accepted by most. But like you say it's incredibly taxing on us... and very unfair for us to suffer it all.
