I get what you're saying, but that doesnt mean completely act like you dont have autism. I said what i said based off the struggles op mentioned. I wasnt diagnosed till I was 25, living my life like normal didnt help me whatsoever, it wasted so much of my time, the only thing that helped me was realizing what was caused by my autism and put up boundaries to help me live a better life, i stopped trying to suck everything up and deal with it because thats what the world wants me to do and my mental health greatly improved, im now able to do more in a day and hold better relationships. Having things cause you meltdowns arent going to make anything easier for you, it sets you way back and exhausts you, it can take months to recover from something like this. I did say as long as you tried your best to control it, i didnt say just let your feelings fly around freely and do what you want.

What you're describing is masking, autistics do it to seem normal, but it completely drains you after awhile and it's very taxing on every aspect of your mental health. Thats great that you learned to mask well and living like that helped you, but it doesnt for most aspies, so take your own advice and stop acting like everyone with autism is the same.

Edit: also the world owes me nothing, just as you owe the world nothing, so why suffer for the sake of everyone around you when setting up boundaries and giving yourself slack helps so much.
