This is a capitalism thing.

Its OK, nothing has been original since humanity existed. Let that absolve you of anxiety. Nothing you do matters or is original. Thats how I think anyway! Actually makes me be more creative without worrying. 108 billion humans have lived and died already and we know like 50 of their names. We dont matter, and its great!

Yes I think its partially a non NT thing, its called sleep revenge. I spend all day thinking about things I'd rather be doing and having fun on than workin, then get off work and want to stay up late to do it all. Usually I just get overwhelmed because there isnt enough time and do something like read a book or do dishes.

This is an autism thing?

Nope

Some replies are saying it's an everybody thing, but I'd argue that neurodivergent peeps on average experience more stress than neurotypical people (friction from the world not being designed for us) so tend to engage is more coping behaviors...like revenge bedtime procrastination
