Help us keep a roof over our head please

Im a single dad to a child with special
Needs.
Two years ago I found out my son was on the autism spectrum.
Do to moving out of state for a “better” job.
I earned a few dollars over what the government allows and we lost our insurance privileges for him.
Since then we paid hundreds of Dollars a week for different kinds of therapy.
ABA therapy, play therapy, aqua therapy.
They cost us hundreds of dollars a week
But for our son we will do anything.
My ex wife works part time so she can spend more time with him and I took upon myself to pay both of our rents so she can teach him skills at home.
A few months ago I lost my job.
I borrowed money from a friend to be able to pay our rents.
A month later I borrowed from someone else to pay the other friend and now can’t pay rent for either me or my ex.
Do to non payment Im about to loose my Appartment and car.
I will be living with friends. (Couch surfing)
And looking for a job, but nothing will pay me fast enough to pay all my bills without sinking in to a deeper hole.
I don’t care about my self but I have to make sure my son will have a roof over his head.
Please help me to go back on my feet
