Heavenly Father,
I need you Lord to help me and my family. The conflict within my family. It have caused separation and now me and my husband is homeless. We praying unto you Lord.I need you Lord to reveal to us what to do. Lord I don’t want to continue to lose hope. We surrender ourselves to you Lord. We ask for forgiveness of our sins. We want to become new creatures in you. We need your everlasting help no longer temporary help. Change us and make us whole again. So we can do the work you have for us to do. In Jesus name I pray Amen 
Some shelters help families get back on their feet. You might try calling around to see if any can help with your specific situation.
Otherwise, If you can travel, I reccomend finding a neutral location where the temperature and weather will be safest to live in your car. Not too hot, not too cold.
In Winter, get the warmest sleeping bags that you can. And Hot water bottles- get hot water at a gas station. And position it under the blanket to build up heat, but make sure they are not touching skin to prevent burns. Layers of blankets help. One method is one under, one or two over. The hot water bottle can go between a layer. But make sure it is sealed.
Get the cheapest gym membership you can. This provides the cheapest way to shower. Otherwise, truckstops and gas station sinks. Find places with locking bathrooms and move quickly. If they know you are washing you wont be allowed back.
Make friends where you can, and stay on people’s good sides. Upset people and you will lose resources.
Food banks will get you free food.
A lot of places are setting laws against homelessness. Safe spaces are shrinking. Do a google search for places that are more welcoming where you wont be put in jail.
Fill up excess space in the car as best you can. Less space will keep you warmer for longer. The trick is staying comfortable.
Good luck.
