Getting My Life Back

Hello, my name is Nelkis and I have 3 children. I'm on my 3rd car this year. I had a pathfinder that I could not afford so I returned it to the bank. I then purchased a Honda that was sold to me with a bad transmission, now I have an Audi that needs some unexpected repairs and the parts are so expensive. It's not worth selling I've invested about 2500 but I recently lost my job and moved due to DV everything went down hill all at once. I signed up for school. There is still so much to do but with out a car it's nearly impossible to get everything done. I feel paralyzed without my car it's nearly impossible to get everything done and I'm not use to relying on people. Please help me with this so that I can help myself. I just wanna give my kids the life they deserve.
