Mom & son escaped domestic violence need help to get on feet

My adult, autistic son and I have been living in a car for a year and a half after escaping a domestic violence situation. While I have been able to get my commercial driver's license through a grant, I am unable to take over-the-road truck driving jobs because I don't have a safe place to leave my son, and I haven't had luck with local jobs. Arizona has been very unhelpful in this situation. I need money to get housing, but to be able to work to get that money I must already have housing.

This area is very expensive, Arizona does not have programs to help my son, and we want to move close to family and friends. I only need temporary help for a motel and necessities for my son; just long enough for me to start earning enough money to pay for things myself and move us to a place where we have support, or until I can take my son with me as a passenger, whichever comes first.

Please help, if you can. Any amount you can offer would be greatly appreciated. Thank you for taking the time to read this. And thank you in advance for your help!
