I never wanted extra time in exams. My brain works so well in so many wells thanks to my autism. I've genuinely never seen it as a drawback. The only time it's a problem is when people decide it's a problem.
And the problem isn't that I don't want to assimilate, I simply don't understand how. I don't know how to make a joke. Whenever I try to tell jokes I'm told my joke is weird, or offensive, or disrespectful. I don't understand the rules of humour so I shut my mouth and get on with my work.
I had a conversation the other day with my parents about how I should respond to "how's your day going?" When is it appropriate to be honest if you're having a bad day? How do I tell if someone is saying that to start a conversation, or just saying hi? It's tricky. So I say, "i'm fine". And then people tell me I'm being rude or laugh at me.
Remote work might also be a good option. A part from the anger your written communication doesnt seem affected. I also understand not loving getting cat gifs but if that's part of the office culture you have to make some attempt to assimilate.
