if you're not sure about heading back to school as others have suggested, there's many 'free' enrichment courses offered by various universities to take online. Which you can do to see if it's something you might be able to handle.
truth of the matter, you better prepare for the long haul in that situation because to make enough part time, many of those kinds of jobs are at the graduate level. though don't get me wrong, there are also many high paying jobs you can get with just picking up a couple certificate or a technical degree, too.
nursing and allied health jobs are in demand at all levels - it's better if you're a RN and have at least a bachelor's, where travel nursing has its perks - if you want to work less months out of the year but full time shifts. cosmetic / health spa nursing is another route that's often not discussed but it's an option to work less hours for higher pay but it requires upselling and getting into it can be difficult because it's not an official, 'structured, career path. . so getting experience and training is something you have to seek out yourself than finding schools readily available.
There's a couple sites you can explore where people sell their skills -- a lot of creative and tech, but many other service options too - where potential hires don't care if you have formal education and happy with self taught. Or again, might gigs that require time and personal accountability/responsibility, such as some security jobs or house/pet sitting/dog walking, etc. Some of that you can get experience by volunteering in your community while you work and if there's a local demand or you find enough steady remote (online) work, then maybe you can quit your day job.
but also the realities when your income goes up, often so does your quality of life and in turn, often your expenses unless you're just completely frugal.
There's a wide variety of side hustles that people do to supplement their income.. it's not usually going to make you rich but if you've got the spare time, it might just give you some extra income.
crafts are a popular option as it doubles as a hobby for most people. So, it's something that even if it doesn't make money or money at first, it provides entertainment or personal fulfillment. cruising through sites like etsy can show you how many no/low talent things make money with the records there of how well they sell. I know a girl over there that all she does is make fabric twine - stripping down old clothing to bind together in thin strips to use as rope or yarn. It's something she can do on the bus or while watching tv, it's a mindless repetitive task that doesn't create any more stress or take that much effort for her to do. It's just a little pocket change to keep her afloat.
I do a lot of side hustles myself. I do what can when I can. some only every few years when the opportunities present themselves. --
I've helped cleared neighbors of trees and branches and turn around to sell it as firewood or craftwood.
i garden for myself and a volunteer gig but I occasionally sell my own, too, the practical biz is selling live plants and seeds.
I live relatively close to a university, used furniture & small appliances is practical beween the end and start of the school terms.
I've gone door to door sometimes just offering to seal people's driveways when I've been hard up because it's a low investment expense on my part that pays for it's self quickly without having to turn tricks.
turning tricks. most of us would roll our eyes at the suggestion... but let's be real, we know it's an option available, too. normie jobs usually have a moment like your ham incident that make us feel like u whores... so, it's not a huge leap to consider it a viable option. not all that are inherently sexual
there's always options to earn extra income with what might be little effort to you.
personal fulfillment is another issue entirely, tho.
