Family Must Move ASAP, now w/o car

On disability,  with one teenage son still at home doing his best to be a great student facing senior year, it's just not fair to him,  we are forced to move from house we have lived in for 14 years, need to get debris box ($516 final tally) after inside water heater leaked  causing major damage of mold to our belongings, much of what we were counting to sell in the downsizing...transmission failed and that really threw things into a spin...just offered a very reliable used ex-detective's car gov maintained twice weekly with only 56k miles for $3000 this is critical for us to do what it takes to find and secure housing again in a housing crunch, this area is not public transportation friendly in the hills especially where we have two options to rent now...
deposit on a new rental plus rent has gone up so much... a one bedroom is $1000 more than what we've been paying for this four bedroom house...
Putting off surgery because we need to relocate without money to do so, I'm not very good at asking for help but I haven't a choice at this point.
We are desperate, simply put..by August 5, 2017  we will be homeless and without a vehicle, I've never been in this place of desperation before, and it's further triggering my disabilities quite remarkably.
My mother has become very ill, three long hospital stays nearly back to back, this has been a very difficult year so far...
In  addition my emotional support animal needs vet care...another $300
I can verify to anyone who wants verification of situations stated.
child support owed to me is in arrears  $46k higher now, took this screenshot just now
which is beyond sad, I've managed to raise all three up to this point, with little help.
Sadder yet is I don't want to shame my sons by posting this to social media so I'm not sure if there is any hope here on gofundme...as you know I finally had to post this, breaks my heart
