Find ways to fit in, mask and accommodate as best you can, rather than expecting the world to be open to you and your quirks because it isn't and won't be. Especially the world of work.
Bloody hell, this is terrible.
Let me tell you about working life, as opposed to school @AnxietySloth. You can choose what clothes to wear. You can set your priorities. You can choose the food you eat. You can work early in the morning, late at night, on projects followed by breaks or daily or every other day. You can choose to make no money and live in a caravan in an intentional community in rural Wales, or be self-employed as a stockbroker in Canary Wharf on a diet of Huel making ££££ by playing the market. You can meet people who you are interested in, rather than be forced to rub along with them for seven years at a time, and ditch people who aren't good company for you.
I've a Level 2 diagnosis (moderate needs). Put me in an office environment with a commute and that will be very apparent very quickly - too loud, too people-y, too much make-work usually. Instead, I run a small charity (not ND related) and help hundreds of people a week. Volunteers love me - they keep turning up, for one! - because I am straighttalking and everyone feels valued and knows that if a shift is on, there's work to do. In my spare time I walk dogs, and again I fly in my work because the owners know that they can set a clock by me and that I love their dogs like my own. I don't often disclose, but I do not give a moment's thought to fitting in. It's exhausting and unhelpful. I'm myself, I'm a good and valuable person as I am, and my values and norms are no less acceptable than NT ones. That's before you get to the fact that there are many ways my autistic brain is better in my lines of work.
I'm all for not using a diagnosis as an excuse and I hope that that's what you meant, but what you wrote doesn't sound like that.
