Help widow to work

I'm a widow with four kids, I spend money on them. I had a car and I roped. I was using the car to deliver, so I could spend on my childrens, but now after the car roped, I can't spend on them, I didn't have other job, and i haven't an insurance, so I want to buy a car to work on it for delivery to gain money and spend on my childrens, and pay the rent of my apartment.
