My story is very similar to yours. Seeing a sleep doctor I was diagnosed with Idiopathic Hypersomnia, then later Narcolepsy.
Same memory issues, mental health issues, physical health getting worse year after year throughout my whole 20's. I found out just a few months back I actually had Lyme disease for almost a decade, that had gone undiagnosed and untreated.
In the US, what about a state-level constitutional amendment lowering full-time hours from 40 to 35? It just seems to me that public support isn't even there right now for something like that, but that support is necessary for getting there.
A basic income, even a very low one, would be another way to get there. We could do away with the idea of full-time / salaried work entirely, and everyone is just part-time hourly. People could work enough hours just for subsistence, or more up to whatever comfort or consumption level fits their desired lifestyle.
If a person believes their paying job is at the core of who they are, they are either very lucky (working a dream job), or very unlucky (overworked, unfulfilled, and/or indoctrinated). All people, not just the wealthy or beautiful or lucky, deserve as much freedom and autonomy as their society can provide to them. Every person deserves a chance to become a great thinker, visionary, artist, scientist, craftsperson, and you can't do those things without plenty of free time to explore and experiment.
Wanting a better world and believing it's possible is the first step to getting there.
Leisure doesn't have to be indulgent. It simply gives a lot more possibilities. If you could work on any project or interest or hobby you wanted to right now, what would you work on? If you could learn any new thing you wanted, what would you learn about? Any family, friends, neighbors, or others going through a hard time right now, how would you like to help them? This is the sort of stuff we should be teaching kids in schools too, about the possibilities of free time. It can be about a lot more than just recovering from the exhaustion of work.
Volunteerism too, providing services or simply comfort to others free of charge, whether they be family, friends, neighbors, the elderly, the sick, the poor, is a non-free-market activity. The less free time a person has though, time away from market-driven, payment-required jobs, the less freedom they have to: work on tasks pro bono, pursue hobbies, interests, contribute to a vibrant caring community, participate in government or petition it, learn new things, experiment, think, write, get creative, explore, and simply pursue their own happiness in life.
