Needing to go home

I am attempting to raise money to be able to move my soon to be 11 year old son to Pennsylvania from Arizona to be close to my family. My wife decided to end out marriage as of yesterday and I do not have anywhere to go or the funds or credit to get a place to live of our own. I have absolutely no support in Arizona either.  My parents passed away in 2014, so I cannot ask them for help, or I would.
