Been there in the past, but I actually have been doing all of the above past couple of years.
I recently read Peter Kropotkin’s The Conquest of Bread on anarcho-communism, and am currently reading Fear and Loathing in Las Vegas by Hunter S. Thompson. I’ve been drawing geometric patterns, mostly based on the Islamic tradition of geometry, and after drawing the patterns I start painting to add some color. I throw them away after a while, but I just like the flow-experience of painting/drawing, don’t really care about the end-result. I’m studying French on a daily basis, mostly on Busuu, but also by watching French movies (most recently Le Proces Goldman) and reading French books (most recently Le Petit Prince). I watch on average 2 movies per week at my local cinema, got a subscription there, sometimes go with friends but I also often go alone. I enjoy going to museums and studying art history, so when I have the time I cross the country by train and make visits. I also take psychedelics (LSD and/or psilocybin) every 2 or 3 weeks. Psychedlics are a lot of fun, but I also actually believe they helped me grow as a person, from what the OP describes, to where I am now. Psychedelics aren’t for everyone, but still I’d highly recommend most people to try them out some time (responsibly of course).
Same here though I use Busuu. Used Duolingo in the past, to be fair there’s not that much difference between the two.
Been dreaming of a FOSS alternative, where people work together to make the best possible ever-improving courses, and all is free and customizable to your every need. That would be so awesome ! Surely some day some one will make this happen, right?
