Have you thought about starting a Patreon at all?
Not to piss others off here, but given your circumstances, I think you'd be forgiven for doing a job that enable yourself some sustenance and to provide care for your parents.
I'll use myself as an example. I too am tired of it all, but rather than going Doomer mode as some do I went full Quixotic Hope (which is a naive and foolish mindset, but I'm a bit of an absurdist stoic so ymmv).
I mention this as I care for my sister who is disabled due to a drunk driver t-boning her car. Our parents are deceased, so it was either going to be me looking after her or… Well, the choice was obvious.
I quit my passion job to take on a job I don't love but can do, am at least content to "put in the hours" and you're damn sure I get everything I can from those motherfuckers (I'm the quintessential "bad" employee who's too good at what they do to fire).
Man this is rambling so I summerise…>tl;dr
For your parent's sake, fight for the revolution by spending the best of what time you have left with them.
Do a job you can do, a hand or head skill, a job you can do well and get paid well for that you hold leverage in, and leave the heart skills for until you can break free financially or socially.
Failing that, you are part of something greater so perhaps creating Leftist Smut is a niche you can fill to stick it to the system. Get that Twittershit, Patreon, the full kit-and-kaboodle of profligate degeneracy that the capitalists utilise, their machinations of repression. Take that and take what you can of it to make it yours.
Plus, if you set those up, I'll sling you a dollar or two on a Patreon/.io/star whatever the fuck there is now, and I'd like to commission you too. So at least for one more day you have some way to support yourself and parents.
For what it's worth, we can support each other. Isn't that half the point after all?
