Car repossessions

Can someone please give me insight on what can be the best option for me. I’m trying to get back on my feet . After a year of not working . Missed car payments , credit card payments I found a partime job that pays 17.30 for now . Next month I go to 17.60 . So obviously I need to cut out some bills to help save something . My car is fucked up it needs rotors . Tires. A new door and front bumper also I had to turn my plates in for no insurance for 3 months (January) . My bills are $850 rent , $260 car note . $100 daycare, $30 phone bill , atleast 40 on water/sewage once I pay this last $200 to get up to good balance , and a $1400 credit card bill .my original thought was to pay the car , try to order car parts and get it all fixed up but if I’m only working partime right now something has to go and since it’s all messed up and have to sit for 3 months that’s not the most important thing on the list . But how does repo work? Wouldn’t I still have to pay the bank back ? Wouldn’t it be very hard to get a car in the future if need be ? (Id rather have no payments anyways. Pay cash for a car) also my lease is up in may I need to try to get my credit up just enough to be able to move or I’m going to have to pay a extra security deposit (which I’m fine with if I have to ) if anyone can help me out on what I should do
