I think I would try to sell unnecessary things, if it was not enough I would consider asking for help to someone that I trust. I think it is important to be prepared for such situations and save some money, because you never know.
that's like my activity when i need fast money, i sell my vga or sometimes i sell my smartphone.
now i prepare my self for sudden emergencies with saving some fiat, so in future i can use it .
Well this is also what I am doing when I am desperately in need of money. But what I am doing first is that I am using my savings. But when my savings runs out this is going to be my last option to sell something and going to sacrifice that just to have money for my needs. It is better to sacrifice those things than to make your hungry into death.
