SINGLE MOTHER NEEDS HELP

Hello I'm Latresa. I'm a 37 yr old single mom of one. I have a vehicle that belongs to my ex. My ex has been threatening to take this vehicle from me for months. I cannot afford the down payment for another vehicle. To be honest the vehicle is in my ex name but all funds for the vehicle have came out of my pocket. I pay the car note every month. I just don't have the funds for a down payment for another vehicle. That is why I'm coming to America for help. I'm a single mother of one wonderful son who is legally blind...I need transportation to get him and  myself around.  I don't know what I would do when my ex takes this car from me. I have until January to get another car..If you can help ...please do. ..if you can't ...please pray for us. .Thank you.
