I didn't enjoy being a kid at all, but being an adult I do like, don't mind working because they pay me.
"Everyone else got it" is a stretch.
It does sound like you are carrying a lot of trauma, I don't want to minimize that, but if you are able bodied, can see and hear and move and think, you are ahead of a lot of people. If you live in a developed nation, you are ahead of a lot of people. I don't think even a majority of kids get the idealized childhood you think they do.
If you have no kids or obligations - what I did was get a lot of roommates to get living cost low and yeah, did just work a minimal job and hang out for a few years before sort of getting more serious about work. Never did the career ladder thing but did get a good job and I can say with absolute honesty - it got better.
