Widow mom of 3 needs safe reliable vehicle

My husband died June !7, 20!8 leaving me with 3 boys ages 13, 10 and 7. I am still dealing with three grieving boys and work when I can. I do deliveries and my car is in bad shape. My doors do not work. It needs brakes axles and catalytic converter. It is very small. I need a van to transport the kids to appointments and other events and to work when i can.
