Pittman Family Vehicle Help

Im Tamisha Pittman and on 7/9 my girls and I wrecked when my car failed to brake in a blind curve slamming us into the back of a garbage truck. God protected us and I thank him numerous times daily for it. But now I'm without a vehicle and don't have the means to buy another. My husband is in a wheelchair from a accident 5yrs ago and I'm his caregiver so we are on a low fixed income. I'm trying to either get enough to buy something used or a down payment for something used. Im struggling with everything and I would be grateful for any help. God bless everyone
