Without sounding mean if I was in your circumstance this is what I would do
1) Go directly to DSS and apply for Food Stamps, WIC Section 8, HEAP, Welfare SSI Medicaid and any other government program there is , Just to be able to pay some bills and be able to put some food on the table and pay rent.
2) After I had at least some backup Id start to look for a JOB. Instead of schorring people for money, how about Schnorring them for a JOB. Id be spending all my time browsing the job websites asking anyone I know about a job. Id walk into stores and ask to fill out a job application (Most jobs arent advertised)
I have to second this. The US is a medinah shel chessed, and they will help if asked.
Hatzlacha on finding something.
