I am in the very same boat right now, since 3 years. I had to sell lots of my personal stuff, my old computer which I build myself, my Smart TV, old Samsung phone (I got an used Huawei since then, and it it good), Apple products, my bed (Yes, I am sleeping on a mattress on the floor, and it is healthy. No back problems anymore), I had to sell shoes, boots (Fashion). I also got food from friends and so on.

Now, what I do is living from low money. I do get only a bit of my parents (Which is too difficult to talk about) and I am eating barely meat, most vegetables. I ask in the supermarket for bananas or anything to get in a lower price. It works, always. I go on evening, where the vegetables (Packed in bigger packages) are getting a lower price due one of them mostly nt eatable anymore, but the rest pretty fresh and normal.

I am barely cooking, eating raw vegetables. Lentils, Potatoes or chutneys are very very low in price, but very very healthy in a meal. With that, I barely need money for that. I have the luck, that I am allowed to set my own plants on a field near my house, for free. I can get most of herbs, chili or potatoes from that as well.

There are many, many many many possibilities someone can do. At first, before I go to others, I am trying of my own. Selling, doing myself and starting to learn, of how low money I can live, and that happy! I even send money to someone to america, even through I had barely Anything! Just for help. But seeing that most people dont have much, is always getting me to describe of what is doable and what not.

I wish you good luck and that you learn how to do things of your own to live without much money you have to get from someone (Sister, Family or whatever) until you get a job.
I am sure too, that if you search and ask, you can get a bit of money with helping old people with their dogs, children. There is ALWAYS someone, that would do that. Just work in the garden, for the dog/cat, kids and then you get some. I did shopping for older people in the neighbourhood, taking care of their garden, picking their fruits from their trees, cutting their trees, cleaning their house and and and
