My car is irreparable and I need help to get a car.

Hey everyone. My car has broken down after my last trip, and I'm at a loss. I'm a single mom and need transportation for me and my 2 girls. I'm struggling through life as it is (as everyone is) and don't have the extra income to buy a car at any price. I'm embarrassed to say I need help. Anything that can help is much appreciated. Without transportation, I can't go to work or get my girls to and from school. Thanks for anything.
