low income family of 4 in dire need of car

I am Alyshia I have a husband and 2 little girls. One is going to be 2 in feburary and the other one is 6. Today I went to go get our only car looked at and we found out that we need a new engine. I have just put a new starter in this car got a new battery and new tires, so I'm very disappointed that it's now going to cost more then it's worth to fix. So now me and my family are out of a car. I currently am out of work due to having to stay home and help my oldest with school and take care of my youngest due to covid. My husband is the only one working and he works a minimum wage job and can only get maximum 30 hours a week so money has been very hard for us. This virus has impacted our credit score and we are unable to get a auto loan at the moment as well.  Any help at this point is appreciated. I don't want to walk in the cold with my almost 2 year old and 5 year old all winter and I'm scared to take the bus because of this virus. I'm a high risk because of health issues and I visit my grandparents on a regular and don't want to put them at risk. Please share this so hopefully it can get enough awareness to help my family out in a hard time.

Happy holidays!
