Hello, fellow urbanite here. It has been tough lately for me as well, thankfully I am still in school.
Potential Work Options:
If you have a college degree, there are English teacher programs in East Asia, you would need to apply for it and get a visa. But from what I've seen, the qualifications don't seem very high. Worth a try, I guess?
Try Amazon Mechanical Turk if you can't find a job. I haven't tried it, but I heard it's better than nothing.
Unironically, panhandling is an option. They look poor, but they make surprising amounts of money. Make a sad backstory or something. I don't know much about this field, however. It will work better in a city where cash is still normalized (like NYC).
Restructuring and Benefits:
What is your diet? Can the foods become cheaper? Rice and beans + cabbages can work for a while. I have survived on Starkist tuna packs (1 dollar per pack) + mashed potato cups (1 dollar per cup) for a while now, and nutrition-wise, I am doing fine. The lack of fiber can be fulfilled by eating coleslaw for cheap.
I used to
volunteer at a food bank and at the end of my shift, I could take a few items. If you can't get a job, a similar arrangement may be an option. If you are in critical need, just ask them for food, they will be glad to help you.
Can you cut out any subscriptions? Perhaps it's time to sail to the high seas.
If you have a pool of cash and can't afford America, there are many nations where housing and food are cheaper. It might be risky, but consider it as an option.
The job market is tough now. See if there are any public benefits you can get (you just fill out a short form online), if you can get unemployment benefits, and if there are technical training programs that might give you a stipend. It will take a week or so, but if you get approved, you can sleep easy.
Misc.:
Do everything to avoid homelessness. Once you go into that pit, it's hard to climb out of it. Avoid the
shelters like the plague, the employees treat you very poorly and it's hard to sleep. If you are about to get evicted, perhaps rent a car and live there for a while. The cold is bearable, but the way society views you isn't (which is why so many homeless end up addicts).
If you are willing to bet America's future is bright, go back to university and get student loans, for a field that has a bright future. If the future is bright, you should be able to pay them back quickly. If you believe otherwise, focus on cutting down all costs.
Regarding Arts:
Arts are saturated right now, there are also a lot of art school graduates looking for jobs and making their own crafts. The entertainment industry in America is not doing well, so a lot of people are also freelancing. The arrival of AI art doesn't help. It seems to be a dark era for your skills, which are being automated away. The general economy is also unhealthy, so there aren't many asking for commissions anymore.
That being said, if you want to sell art, find an underutilized fandom that still has a demand for merchandise. Many fandoms have significant amounts of people, but their owners don't make good merchandise for them, or the fans want "unique" stuff. Make consumerism your friend.
If you want to draw original stuff, you need a following, and to get a following, you need to start by making fanart (or making connections, but that also takes time). People start on Newgrounds, DeviantArt, etc. Use Reddit,
Facebook, Instagram, etc., and go to relevant threads to advertise your art. If people like the show, they won't mind the art so long as it features the show's character.
Connect with fellow artists on Xitter/Bluesky/Discord, and build up a reputation. The art world is filled with nepotism and favoritism, so you might have to go to a few gatherings here and there. This won't be easy. However, once people like you, they will be the ones coming to you asking for art, instead of you having to actively market stuff. Perhaps make a
Patreon also?
I personally recommend art as a hobby, because just like sports, most people can't survive off of it. But if you are determined, perhaps you can make it.
You said you are in a city? Alongside food pantries, public benefits, and networking, you could try selling art on the street. A tourist destination (or anywhere with foot traffic) will work, but make sure the local authorities are lenient. Ask the street vendors already there if they needed permits, and also ask nearby authorities about any unspoken rules.
I wish you the best of luck in these difficult times.
