How do people adult ?

Seriously how ?? I just moved out & I've already got my car repossessed bc the car dealership couldn't verify my employment which resulted in me losing 2000$ the ONLY money I had for a car. That just ripped my heart out bc I worked so hard saving up that money and I feel robbed, there's nothing I can do about it either. My rent is due on Sunday and I have NO money at all to pay for it, it's one of those week by week things so no I can't ask for an extension. My parents live in another state and can't help me out. I'm scared what's going to happen on Sunday. My husband had to go to traffic court because a couple of months ago he was pulled over & was given a ticket for no insurance when we had insurance we didn't have paperwork only the Geico app which the cop didn't care still wrote him a ticket. Judge doesn't care told him he has to pay 190$ within 3 months. I'm like dude we have no money to pay our rent this is the last thing I need to be worrying about. My parents keep badgering me to come out for thanksgiving and I keep having to tell them I have no car you guys I'm trying to figure out my living situation. I'm not even thinking about thanksgiving or Christmas nothing my daughter will not miss the excess amount of food or no presents bc she is 2. Yes it's breaking my heart but she will notice that she has no where to sleep before anything. My job works me 3 days a week I'm looking for a job but it's so challenging without a car the bus where I live is 2$ to me that is just crazy but I still pay it. I'm just ready to break down. It seems like there is always something that goes wrong and just stays wrong. I don't know how people do it.

Edit: Kayla that was my exact argument. They let me drive off the lot had the car for 2 months suddenly they said the finance company can't get ahold of anyone even tho I know for a fact they spoke with multiple managers at my job about me , they said that because there was no landline(?) the business is not legit. I work at a McDonalds that's privately owned. I'm surprised they were able to get ahold of as many people as they did, no one can ever get ahold of any upper management. My husband felt like they purposely ripped me off & was telling me to keep the car & just let them catch us whenever but I was too afraid of the repercussions so I just took the car back I guess it wasn't "repossessed" my loan went into default. I literally cried to them this is my only car I gave you the only money I had can I get my deposit back & because I signed a contract and because the time to return the car (within 2 days) ran out I'm assed out. I was so furious telling them that they are ruining people's lives w their incompetence, my employment should've been verified before I drove off the lot. They literally threatened to charge me w possession of a stolen vehicle & giving false information. I was so flabbergasted like wooow How is it my fault you guys can't do your job ?? All they could do was say sorry after I returned the car. Like you guys are so wrong it's really fucked up the things people can get away that are perfectly legal.
